I read this book months ago and it keeps resurfacing in my thoughts -- a good indication that this is a powerful story. All her life, twelve-year-old Ada has been raised by her father David Sibelius, who home-schools her and takes her to work with him at the university computer science lab, where he and his colleagues are working on early versions of artificial intelligence. Ada is a prodigy who can code, talk physics or analyze literature with her father's friends, but she has no friends of her ...more

AWESOME NOVEL!!!!!

"Shouldn't she have recess, or something?" Liston once asked David, several years before, when she noticed Ada becoming pale from spending every day inside the lab.
"Agreed", said David, and so every day at lunch he had begun to march her around the
Fens for thirty minutes, observing the flora, naming the birds by their songs,
pointing out where Fibonacci sequences occurred in nature, once finding a mushroom that he said was edible and the cooking it up for the lab. Sometimes

I don't even want to analyze all the things I loved about this book. I just want to relish in that experience of reading a book that finds you at the right time and touches you inexplicably. It's a remarkable story, beautifully written and told, and I can't recommend it enough.

I finished this some time ago and still can’t find the words to explain how wonderful and perfect this book is, how after turning the last page I went back and started the first again with a new perspective. Why is it that it’s so much easier to describe the feelings for a not great or so-so book? Ah, love, it is a many splendored thing.

This is a literary and emotionally-powerful read, a cerebral page turner that straddles multiple genres, yet the narrative never becomes bogged down in its aspir

For Ada Sibelius, the center of her universe was her scientist father, David. He raised her on his own, homeschooling her, and every day he took her with him to his job, where he directed a computer science lab at the Boston Institute of Technology. David treated Ada like an adult, encouraging her to learn as much about the lab's work as she could, interact with his employees and graduate students, and develop her own theories about the work he was doing, trying to create a computer truly capabl ...more

Fifty pages from the end I thought I had my review formulated. I was going to suggest Liz Moore had used the wrong voice to tell this story. I thought it should have been told in the first person and not the third to sharpen its focus and avoid awkward POV shifts. However the very clever epilogue shredded my argument and made me re-think my entire reading of the novel. In other words she produces a tremendously clever trick at the end of this novel. All of a sudden I began to understand why this ...more

2.5/5 Stars

Contemporary is a genre that’s totally outside of my comfort zone, and I think of The Unseen World as just an okay contemporary book with some mystery element.


I won’t be talking about any of the plots at all, anything I say will seem too revealing and believe me, this book’s plot is immensely predictable already right from the start; at least it was for me. The Unseen World has so many potentials, it’s a good book and I’m not going to deny that I finished this within two days of readi

A phenomenal book about a young girl's quest to discover her beloved father's secret past, The Unseen World slayed me so hard that I have to give it my first five-star rating for a full-length work of fiction in over a year. The story follows Ada Sibelius, an observant and shy prodigy raised by her brilliant and quirky father David, who leads a computer science lab in 1980s-Boston. Though awkward and uncouth, David always provides Ada with his company and his intelligence, so much so that by age ...more

Ada Sibelius. What a Remarkably Drawn 14-Year-Old Protagonist!

This is a coming-of-age novel unlike any I can readily recall. Yesterday morning, after finishing it, I was ready to say 3.6, thinking then it may have been 50 pages too long. The novel did not affect me with a strong emotional reaction such as utter sadness upon finishing a few novels. This novel impacted me in ways that are much more subtle and rather more profound . Please bear with me in my too-lengthy explanation of this bold st

Think brainy. Big brained, intense, abstract thinkers who live in their heads but who come out to play with the ideas of others and play with others who love creating, analyzing, puzzling over, observing and sharing ideas - that's the life of Ada Sibelius, daughter of eccentric genius David. She is geeky, homeschooled, socially stunted and just slightly aware of her unusual situation.

Ada is confronted by an enormous puzzle, among David's cohorts who are cryptographers, mathematicians, code solve

*1.5/5* (for some reason, a bottom-of-the-barrel 1 star just feels wrong. this one wasn't THE WORST, I just really didn't enjoy much about it)

From the beginning, I got bad vibes from this book. There were pages upon pages of tech speak that bored me, and I found multiple inconsistencies in the writing that bugged me to no end (ex. somebody walks into a room, then seconds later, is described as walking into the room they're supposed to now be in... makes no sense).

Wonderfully touching story that really grabbed a hold of me with unique characters and it's slow and steady unveiling of past secrets and lies....

Ada Sibelius came to be through the assistance of a surrogate mother named Birdie, and was then raised by David-her quirky Scientist Father in the early 70's. Ada is essentially raised in the science lab that David oversees. She is home-schooled, so her only interaction and other human contact outside of her Father comes from the lab associates, who be

This is a beautiful, profound book that requires a deep level of commitment and investment from the reader. It's a slow burn, there's not a lot of dialogue, and it's 451 pages long. But it's the kind of book that makes you feel like you're in good hands, the kind that will reward you both emotionally and cerebrally if you take the plunge.

I went into it knowing very little, and I had no idea what to expect. How deep would the artificial intelligence aspects of it go? Who were these characters? Th

I’m glad I waited to review this one because it needed to simmer so that I could better appreciate it. I needed distance in order to clearly see the masterfully-drawn, tremendously human characters in this moving story that stretched far into the past and well into the future. Perhaps a bit longer than it needed to be and for me not quite as powerful as Tell the Wolves I’m Home, this one, too, is a coming of age tale about (among other things) relationships, love, and the lengths we go to prote ...more

It has been a long time since a book captivated me from beginning to end, but that is exactly what happened with this book. The story follows Ada Sibelius who is raised and homeschooled by a single father, David, who is a brilliant scientist. As David’s memory begins to fade, Ada is forced to move in with a family friend and then hunt out for the truth of David’s past. The plot is propelled forward as Ada slowly discovers more details about David’s life, but the real heart of the story lies betw ...more

Born in 1971, Ada Sibelius is a twelve-year-old prodigy, and the daughter of an enigmatic, scientific genius, David Sibelius. David is director of a prestigious computer science laboratory in Boston that gathers the best minds in the field. An only child, born through surrogacy, Ada was homeschooled (more like “lab-schooled”) by her unorthodox father and became an integral part of his colleagues’ lives, especially his best friend and close colleague next door, Diana Liston.

Such an unexpectedly touching story that kept me up at night (and very tired at work) for nearly a week. It finds the perfect balance between its components - the central father-daughter relationship, typical coming-of-age elements (intense first crush, feeling isolated at school), artificial intelligence, Alzheimer's disease and a mysterious backstory - without feeling cliche or overstuffed. The novel flips back and forth between the 1970s and 2009 and each section ended with a cliffhanger of s ...more

So yeah, I hit the marriage jackpot, thanks for asking!

This book though. Oh my gosh. This is why literary fiction will always be my bread and butter. I love my genre fiction, my thrillers and epic fantasy and romance and the occasional memoir, and this year I've surprised myself with how much I've enjoyed straight-up non-fiction, but there

So I read this book in almost exactly 24 hours.

My book club picked The Unseen World, at my suggestion, and so of course I waited until the last minute to start it. Don't know why I did that. It was so good. And I never would have picked it up without book club (even though I suggested it), so thank goodness for book clubs. Anyways, I started it yesterday at 10 AM, got through a little over half by bedtime, then woke up early to finish. I got through all but the last ten pages, so I made my frie

He had been pretending, then, to look into his past, when really he was looking into some alternate reality, some different version of his own history, some unseen world.

I always enjoy reading something different, something that can't be compared to other books read before, and I'm happy to say that The Unseen World definitely fulfilled this expectation.

There are seemingly countless "unseen worlds" of various types in this novel. I read Liz Moore's last novel, Heft, and also gave that one five stars. However, in my opinion, she seriously upped her game in turning this one out. Although many reviews have been written already, I feel I must say that I am not a total "geeky" girl (I do not know how to code & never strived to learn), my math skills are probably sub-par, but none of that ended up mattering.

"The Unseen World", by Liz Moore, is completely captivating; while I was reading it I was engrossed - thinking of nothing else. As the story begins, in the early 1980s, our precocious teen-aged protagonist, Ada Sibelius, is being raised by her single-father, David (her mother was a surrogate). David "home-schools" Ada in the Computer Science Laboratory that he heads up at a fictional university in Boston. She's just part of the family there with the other lab personnel along with each year's new ...more

One of the best novels I've read this year.

I loved the characters; I loved the story structure. The mystery went in a direction I was not expecting and I found it refreshing. The writing style was exactly what I like; it didn't get in the way of the story. I found myself drawn to the book and I never had to force myself to read it.

It was so close to a five-star read for me but the ending took a turn that was total cliche and I couldn't do it. If you've read it, reach out to me and I can tell t

The Unseen World was a story that got under my skin in such a surprising way and left me begging for more. Despite being at its core a literary story of the unexpected dynamics of family in what we do and don't know, it also touched on intelligence, both from our own minds and through technology. This mixture could have created a confusing mess but instead is a beautifully written tale with a memorable and truly satisfying ending.

Told out of order, Ada is an intelligent young girl who is raised

Ada basically grows up in the lab in front of David and his colleagues. Thriving on her father’s idea of home schooling which includes mathematics, cryp
