Thaddeus finds out that his baby sister is portal to another dimension that is letting these slug things into our world. He thinks they will be exciting and help him take over the world; they only want to spread hugs and happiness. He is disappointed.

It's not a bad story. I didn't get into the story. I think it wasn't my story. I wasn't crazy about the art either. I'm sure middle grade readers might find this delightful.

Cute baby, cute aliens...bad big brother! It's a light story done with compassion and skill. Best aspect of the book, besides the lovable aliens: Yang is not afraid to show an unsympathetic main character, and he manages to redeem him without getting syrupy about it. The mustache is a nice example of Thaddeus acting self-important with his signature new look, and yet by the end it's become so much more than that, being shared, but without becoming saccharine or emotionally fake. That was well do ...more
I giggled my way through this amusing tongue in cheek comic about a Thaddeus, who is convinced that his little sister is an alien. While not quite true, he does discover that she is a portal for aliens! Of course, no one believes him and believes he simply resents his sister. What I love about Gene is that in fact Thaddeus DOES resent his sister and it is demonstrated in a funny, somewhat subtle way, along with the ridiculous story line of his baby sister being an alien portal.

Somewhat cute book about a boy struggling with having a new sister, who turns out to be an alien gateway. It's a little hard to relate to the main kid unless you're still 10, as he's kind of a brat throughout the entire book. He somewhat redeems himself, but then we're left with no conclusion for everything else. Abrupt end.
This book is adorable and funny. I feel bad for Thaddeus's parents, one of their kids is an alien gateway and the other is a psychopath.

Thaddeus K. Fong can't understand why everybody is so crazy over his new baby sister, Maddie. His annoyance at her inability to say anything other than "ga" turns into amazement at the discovery that these "ga's" come in sets of prime numbers. The only logical explanation for this: she must be an alien.

Thaddeus' discovery is met with mockery, but he finds his proof when Maddie starts spitting up space pods holding small slug-like creatures, bent on world domination! Actually, they're missionarie

Totally adorable and completely unique sibling rivalry story by teacher and graphic novel/comic artist of American Born Chinese fame, Gene Luen Yang. Adorable aliens figure in the story, too, in a very unique and surprising way. Kid story, maybe for tweens if not teens, but the dialogue is terrific for any age. Briefly, Thaddeus becomes convinced by her language that is baby sister is an alien, part of an alien invasion... cute, but smart and inventive and thoughtful, sweet. Yang is the real dea ...more

It was so odd yet so charming. Thaddeus' new sister is getting lots of attention, but he suspects she may be an alien. She only says "ga" in prime numbers. This was so surreal, but Yang is hilarious. I can tell this book is a bit dated because Thaddeus referenced Miley Cyrus as his future wife. If you're a fan of Gene Luen Yang, you will still enjoy it despite the absurdity.

Some adult-like humor may push this very charming little tale into teen territory, which is where Gene Yang usually lives, so that's fine, of course. But the subject matter - an 8 year old boy dealing with his new baby sister and the intergalactic love slugs who hitch a ride to earth through her - makes me want to give it to younger readers. Anyway, love the art as always, love the colors, giggled through the story.
Many older siblings think the new baby is an alien - but what if you had empirical evidence to support your claim? Thaddeus thinks he does, but he's having a hard time convincing anyone.

The premise is interesting, but the ending fell a little flat to me.

The slugs remind me of some I've seen in a different context. If you know where, please enlighten me! Maybe Jason's in Foxtrot? Or maybe all cartoon slugs come out the same...

A short, simple, and very sweet book about an 8-year old who longs to be a dictator, and perhaps discovers a way to save/take over the world when he realizes his baby sister has ties to an alien world. I wish this book was a little bit longer, as I enjoyed the characters very much.

Very cute! Short, sweet, with a heartwarming ending.
This is a "classic" older child convinced his baby sister is an alien story, with an original twist, and a sweet message. Great for kids!

Hilarious, with some of the most endearing space aliens you could ever hope to see.

This graphic novel, deceptively simple, is brilliant. I'll talk about it more when it is officially released.
Eight-year-old Thaddeus K. Fong isn't such a big fan of his pesky little baby sister. Maddie gets all the attention, and Thaddeus is convinced there's something weird about her. One day in math class, he has an idea. After some observation, he's confirmed his theory: Maddie only makes ga-ga noises in patterns of prime numbers. Obviously, she's an alien.

It turns out Thaddeus is wrong, but not that wrong. Maddie is actually a conduit for aliens from another dimension. These aliens, much to Thaddeu

I was cracking up as I read this brief but brilliant volume. The scenario of an older sibling being jealous of a new sibling is familiar enough, as is the precocious child character. But the novel takes unexpected and hilarious turns as the baby ends up being a gateway between dimensions which aliens slip through. Thaddeus hopes that this will mean an exciting apocalyptic confrontation but they turn out to be "Missionaries of smiles and happy feelings" and even when he kills one of them, they ju ...more
I have had a bit of a love hate relationship with Gene Yang. He's a great guy. I heard him speak, and he is awesome. Awesome! I mean, he kept his job as a teacher after becoming a pretty popular graphic artist? That is stand-up. I like both his books that are available to a large degree. I like the art in American Born Chinese and I appreciate what they were trying to do in The Eternal Smile, even though I really only like one of the stories. His writing has always been his weak point for me. It ...more

What an odd, odd book. It was pretty hilarious. I really liked it a lot. I say it that way because it was rather strange. The story's progressing and going on, and as I read it I kept thinking, "did that really just happen?"

This is by Gene Luen Yang the same author of the celebrated book American Born Chinese.

Prime Baby, however is all about a baby that only ga's (says ga ga) in prime numbers. Not as powerful a message, if you know what I mean... but plenty funny.

Thaddeus hates his new baby sister. He comes up with a conspiracy theory that she is an alien because she says "ga" in prime numbers (she'll say it once, twice, three times, five times, etc). He starts monitoring her closely, interpreting everything she does as evidence that she is an alien. His sister loves the time they spend together and babbles to him even more. Then one day, she starts puking up these rather large capsules, which are actually space ships for an alien race hellbent on bringi ...more

Thaddeus' sister Maddie is not talking yet; all she says is "ga" over and over again. When Thaddeus starts counting the ga's, he realizes that it only adds up to prime numbers. He's convinced that Maddie is an alien, though no one else believes him. Then, she starts spitting up spaceships and Thaddeus is finally able to prove to everyone that his sister is possessed by creatures from outer space. When Maddie is taken away for observation, Thaddeus starts to wonder if he really did the right thin ...more

Let's be honest here. With all the endless crying and screaming, white liquids with bits oozing from its mouths and noises and all kinds of unmentionable smells wafting from its diaper, how many of us honestly thought our baby sister/brother was actually an alien? In Thaddeus' case, he is absolutely convinced that his baby sister is simply that--an extraterrestrial life form. Unfortunately, no one believes him, including his parents who try to pacify him by giving him access to their credit card ...more

Jealous little boy named Thaddeus doesn’t like his new baby sister and is constantly saying rude and absurd things about her.

Thaddeus realizes how his sister might feel all alone in that place, especially when it’s his fault she’s there in the first

A cute tale about a mean big brother who thinks his annoying little sister is an alien. Well... turns out he's sort of right! She's actually a gateway between dimensions, allowing aliens to enter our realm by, basically, being blarfed out of her mouth, tiny little space-ships and all. Big brother's dreams of saving the planet or gaining world dominion are dashed, however, when the aliens in question turn out to be missionaries, wanting only to spread the word to the world about smiles and happy ...more

There are some authors where I love everything they write. This is not one of those authors. I find that I'm either wildly entertained or disappointed. This time around I was disappointed. It was not a bad book, but it certainly didn't wow me, either. And I was not a fan of the ending. (view spoiler) ...more

The short story equivalent of a graphic novel (what is that, like...a normal comic book?), 'Prime Baby' is Gene Luen Yang writing a doofy little thing about growing up with a baby sibling. It's the kind of book that doesn't resolve anything related to its quirky science fiction elements. We'll never know where the aliens came from, why they're coming through the protagonist's sister, and why they're so chill to be around. We just know that the two leads are getting along, and that's all the stor ...more

This series of strips by the award-winning Yang is a bit darker and more sarcastic than his other works. A patron in my library system complained that it should be YA due to content. The older brother's extreme annoyance of his baby sister could almost be called hatred. When his close observations of her lead him to believe that she's an alien being, he's ostracized at school. But when she actually starts spitting out little alien pods, the plot gets even weirder.

I think the snarky humor is simi
Sibling jealousy with a dark and fantastical element, but still lighthearted and funny. Thaddeus is certain his 18-month-old sister is an alien, proven by the fact that the number of times she "ga-ga-gas" is in prime numbers. He even puts up a YouTube video to prove it. His parents are unconvinced and his school friends think he's crazy. Then one day, aliens come out of his sister's mouth to spread their message of smiles and happy feelings. She is confined to a research facility for observation ...more
