For thirteen years, Ben Tomlin was an only child. But all that changes when his mother brings home Zan — an eight-day-old chimpanzee. Ben’s father, a renowned behavioral scientist, has uprooted the family to pursue his latest research project: a high-profile experiment to determine whether chimpanzees can acquire advanced language skills. Ben’s parents tell him to treat Za ...more

I would read this book over Sara Gruen's "The Ape House" Any day of the week. Unlike Gruen's book, which claims to glean inspiration from notable great ape ASL research experiments, namely, Project Washoe, Project Nim, Koko the gorilla, and Kanzi, this book actually reflects many of the situations encountered while these projects were active. Many parallels are drawn between Zan and Washoe (Roger Fouts' "Next of Kin: My Conversations With Chimpanzees"), including the plan behind the cross-foster ...more

Our capacity for language is one of the attributes often cited as what makes humans so distinct from other animals. It’s a controversial distinction, because we’ve observed other species communicate in very interesting and effective ways: whales sing, dolphins whistle, birds do whatever it is they do to switch places while in formation. Parrots, of course, can be trained to mimic human speech! But there’s a difference between replicating instinctual sounds with fixed meanings and being able to l ...more
Ben is introduced to Zan when he is 8 days old. Zan is his new baby brother. At first Ben is resistant to loving Zan, but that changes as he gets to know him. Ben loves Zan more than anything in the world. He would do anything for him. But others, including his father, don't understand why he has such an attachment to Zan. Yes, Zan is his brother, but Zan is also a chimp. A chimp who Ben's father is researching by conducting an experiment to see if chimps can learn language. To Ben, Zan has beco ...more
I had this book out from the library for months before I could bring myself to crack it open. It seemed so fraught with peril, and I was afraid of it.

It's the story of a young man, the son of scientists, who gets inextricably involved with his parents' experiment around teaching a baby chimp ASL while raising him as a human, or as near enough to a human as to make no difference. It's also the story of a young man falling in love for the first time, and adjusting to school, and dealing with a wel
In the early 1970s, Ben’s parents are at the cutting edge of behavioral animal research. When Ben’s father, Dr. Richard Tomlin, gets an appointment at a university that supports his proposed project for teaching American Sign Language to a chimpanzee, he moves his wife Sarah and 14 year-old son across Canada from Toronto to Victoria. Ben is not too excited about this, nor is he thrilled when his mother brings home an 8-day-old chimpanzee that Ben sees as ugly. They name the chimp Zan (after Tarz ...more
I do not like chimpanzees or monkeys of any stripe. I always skipped that part of a zoo when visiting. Having said that, I loved this book about 13 - 15 year old Ben Tomlin whose parents have brought an infant chimp, Zan, into the family to study cross-fostering and language acquisition. Ben is a typical self-absorbed teenager at the beginning of the book, a typical boy who resents his parents making him move from Toronto to British Columbia. He even resents the chimp who will become their sole ...more

I chose to read this book because I've enjoyed other books by Kenneth Oppel. By coincidence, I'd just heard the NPR "This American Life" podcast about Dr. and Mrs. Temrelin who "adopted" Lucy, a chimpanzee, and raised her as their own daughter--a story which did not have a happy ending. I also had recently listened to the NPR "Stuff You Should Know" podcast about How Face Transplants work and the several incidents of chimps raised in homes who suddenly turn violent and--well, the title of the po ...more
All right, let it be known that I am an enormous, gigantic, honking big fan of Kenneth Oppel. This Dark Endeavour and Airborn are my two favourite books, ever- books I read through fairly often for little to no reason, and books I occasionally sleep with like normal people might sleep with a teddy bear. Ridiculous perhaps? No, because it's true.
Anyways. To the point now. I didn't actually like this one. Usually Oppel's books are very engaging and interesting, but this one, I felt, never went any
In Oppel's latest novel, a boy is raised by two parents who are scientists. They decide to adopt a baby chimp (kidnap) and teach it to speak English. But his father isnt' as nice as he seems.. Is he using the chimp for more sinister purposes? Can the main character accept the chimp as a real member of his family? This book has some teen drama sprinkled into the fold. It was a fairly quick, but emotional read and I really enjoyed the interactions with the chimp, Zan.

This book was a fairly easy read, but I seriously enjoyed it. I have a bit of a soft spot in my heart for animals so it’s no wonder I enjoyed it so much.
*Golden Line*
When the protagonist, Ben, eventually grows fonder with Zan, kinder words and thoughts come from Ben’s brain. Practically any time Ben spoke about Zan my heart melted (cheesy, I know.) Although, one part really stood out to me. Ben’s father had just finished discussing the new teaching tool they’d be using on Ben in the near futur

This book is about a family who got a baby chimp because the father was a scientist and wanted to test if the chimp was able to learn American Sign Language. The whole family, except for the father, treated the chimp like he was part of their family. The chimp was named Zan, which was a part of 'Tarzan'. Ben feels Zan is his baby brother and treats him like it. As time passes, Zan thinks he is human as well. He wore clothes like people and even food at the table. As time passed, Zan started to b ...more

I imagine this book may have been transformative for me if I'd read it as a younger young adult - I loved animals, but I hadn't really considered animal rights, and this book (gently) forces the reader to consider the relationship between animals and humans. The story is about a 13-year-old Canadian boy whose professor parents adopt/abduct a baby chimp to raise as their own in an experiment to see whether or not chimps can learn ASL. I commend Kenneth Oppel for creating a book about vivisection ...more
Cormac's review (aged 10)

This book is about a family who adopt a baby chimp as part of an experiment to see whether he can be taught to communicate using sign language. The mother and father are both scientists and their son, Ben, is 13 when Zan comes to live with them. This is why the book is called Half Brother, because Ben has to accept this animal not as a pet, but as a brother. At first Ben has a hard time with this but eventually he comes to his senses and realises that Zan means more to h

Reason for Reading: Oppel is my favourite YA author and I read every new book he publishes.

This book is something completely different from Oppel's usual fare and I must admit I was a little leery going in, hoping this wasn't going to end up being a platform for animal rights. I need not have worried; Oppel is an accomplished writer and a reader can be confident that he is going to produce a well-crafted novel that will keep one glued to one's seat.

I read this book in one sitting, I was that tak

This one took me by surprise. I wasn't particularly excited by the premise but it seemed different and so I thought I'd see what it was like. Half Brother is definitely something I'd recommend for any Young Adult reader. I was a little apprehensive about reading about a 13 year old, but Ben's emotions and thoughts felt older and they were definitely powerful. Ben was just as interesting as his Chimpanzee brother, Zan. It is a coming of age novel and his emotions were very realistic. The relation ...more
This is a BIG story. Ben's not thrilled when his academic parents adopt (some might say kidnap)a newborn chimp. His father wants to see if the chimp can learn language; his mother wants to see what will happen when the chimp is raised like a human baby in a human family. And Ben's life just has to fall in line with the program.

At the heart of the novel is the question of what it means to be human -- or animal. Can a chimp be equal to a human? How should humans treat animals? What's right? What's

When 13-year-old Ben and his scientist parents leave their home in Toronto to move to Victoria, British Columbia for his father’s important research project, Ben resigns himself to starting at a new school and making new friends. Typically, his father doesn’t seem interested in how Ben feels about any of this, all he can think about is his latest experiment in which he will study the possibility of teaching a chimpanzee sign language. As if the move isn’t enough to deal wi
This is a review on Kenneth Oppel's book, Half Brother. I have read multiple of his books including the four books in the Silverwing series and the three in the Airborn series! From reading these novels, I know that he is an exceptional writer with lots of talent. Half Brother has definitely lived up to all my expectations and might be one of my favorite 'good'reads!

Ben's parents are both scientists but he is shocked when they announce that they are adopting a chimpanzee so they can try to teach it sign language. He isn't keen on the idea and really doesn't want to have to move across the country to be nearer the university that is funding the experiment either. When Zan arrives Ben is told to think of him as a younger brother, Zan is to be raised as a human child and the whole family must be involved along with several students from the university. But wha ...more
Kenneth Oppel is a fine writer and this is an excellent read for everyone but especially younger teens who can identify with the fourteen year-old protagonist Ben. My favorite character was the research assistant Peter who seemed to have the right balance of compassion and common sense. Runner up is Ben's long-suffering Mom. I put her in the Marge Simpson "Why do you stay married to that jerk?" category. I despised Ben's father but young adults' abhor parental divorce so Oppel couldn't do that. ...more

After his parents moved him across the country, Ben has to get used to a new school, make new friends, and become a big brother to the newest addition to the Tomlin-- a baby chimp. Ben is not at all excited about his parents latest research project, which is teach language to this chimp. The moment his mom brought the baby home, he wanted absolutely nothing to with him because he had bigger problems to worry about--getting into an elite prep school, making new friends, and dating the cutest girl ...more

Recommends it for: Young minds with an interest in animal intelligence and animal rights
Recommended to Alan by: Olivia
Drawing liberally on real-life research into simian intelligence and language acquisition, this fictionalized take on Washoe the chimpanzee's life may be targeted at adolescent readers, perhaps, but it's a quick and enjoyable read for anyone who, say, likes Robert Sawyer but wants something lighter. I finished it in a single day, though it took me awhile longer to decide what to say about it.

The book as it stands has at least one significant flaw: I searched in vain for any foreword, afterword,
Last year I bought a book called 'The Discursive Mind', which argued that the difference between humans and animals is, essentially, the ability to communicate. In parts, it talked about the experiments done with sign language and chimps in the 70's, and the difference between speech and communication. While it was a fantastic book, and challenged me to really think, 'Half Brother' asked me to do the same kind of thinking, without the need for 'expert language', wrapped in a story that progressi ...more

Martha and I were just sorting through her bookshelves (Saturday morning tidy up) and remembered how much we both loved this book. Kenneth Oppel was in K-W to be the writer in residence for KPL and he was giving a book talk at one of the local branches so we cheerfully went along with our books to be signed and hear some of his wisdom. He spoke about this book and the Frankenstein series and fielded questions from children and adults who were keen to write.

We probably wouldn't have chosen to re
This was a very well written and thought provoking book. Ben's parents are both researchers and they bring in an addition to the family. It is a baby gorilla that they call "Zan". Over time, Ben becomes very close to Zan and he considers him a brother. Zan is being observed to see if he can learn language and he is treated like a human such as having him wear clothing. The research team is teaching Zan ASL (American Sign Language). On the surface, it appears like the treatment of the gorilla is ...more

I loved this book so much. It's a story for teens, but it appeals to any audience. Oppel wrote his book based on true stories of research that happened in the 1970s. During this time, one particular chimp was adopted by a human family and taught sign language. In Oppel's version, a teenager named Ben becomes a "brother" to a newborn chimp when his family brings it home to study it and teach it sign language.

This book is good because it has a great story and believable characters. It raises lots

Such a great easy read. I can see this appealing to pre-teens. Peter's relationship with with Zan is heartbreaking to read about, knowing from an adult perspective it can't last. I enjoyed seeing the transformation Peter goes through in his attachment though.
