Things to Expect from The Improbable Theory of Ana and Zak:

1.) Two wonderfully-portrayed main characters. Ana and Zak both have very different and distinct personalities. Both were a bit hard to like at first (Ana was pretty stuck up, and Zak was an arrogant prick), but as they continued to learn more about each other and themselves, I realized that I've grown quite attached to them. Both went through a lot of character development, and I

There are moments when I feel really ancient. I think this is one of those moments. I really wanted to like this book but my inner spinster just took hold of me and deconstructed what appears to be a cute story into: characters that lacked depth, an improbable plot that is almost absurd, and a tone that feels more tween than YA.

Like any unlikely love story, both Ana and Zak come from completely different worlds. Zak is a slacker who is really smart but doesn't apply himself, almost to the point

A fun hilarious read about a nerdy girl (Ana) and a geeky boy’s (Zak’s) 24-hour unexpected adventure that starts at a quiz bowl tournament, a sci-fi convention where the two barely survive a hilarious, crazy and almost deadly stuff in search of Ana’s little brother, Clayton. It felt like watching a rom-com movie and I enjoyed it.

The main characters are both very distinct. They’re both the same and different. Both geeks in their own right although one is a slacker and the other an ov

I was going to be generous and give this book 2.5 or 3 stars, but I’m afraid it just irritated me way too much for that.

Ana and Zak both annoyed me in this book, because they were freaking idiots! Who cuts and pastes information from Wikipedia and hands it in at school as an essay (complete with hyperlinks?). Zak. He is really that big of an idiot that he would not only chea

The Improbable Theory of Ana and Zak is one of those laugh out loud, quirky contemporaries with fantastic underlying messages that every contemporary junkie needs to read. It’s definitely a book that I enjoyed, and apparently a spider agrees with me (it’s now dead though). Oh yes, I went to the bathroom the other day and when I came back to my desk, there was a huge ugly spider resting on my book. The horrors. I legit screamed and spent the next half an hour

La improbable teoría de Ana y Zak es una novela juvenil realista cuya historia se articula en torno a la amistad que nace entre Ana y Zak, dos personajes bastante peculiares y que se salen mucho de la norma. Lo cogí sin saber qué esperarme de él y la verdad es que me ha gustado, me ha hecho reír y pasar un buen rato.
Esta novela no me ha parecido nada especial, no tene nada que la haga destacar dentro de lo ya escrito y por lo tanto tampoco la recomen

I think the main reason why I'm disappointed with this book is that I misread the synopsis and it was different than what I thought it was going to be. I thought it was going to be about two nerdy people that fall in love, but in reality, Ana is an all A student who looks down upon Zak and the people at Washingcon for a lot of the book because she thinks she's better than them. That got really old really fast and made the mood of the book really annoying, which took about 150 pages to get past. ...more

Empecé a leer este libro porque no tenía nada descargado en el Ipad y estaba aburrida en clases (shame on me!). Lo vi, me gustó la portada y lo descargué, con pocas expectativas de que el libro, en realidad, me gustaría. Pero, entre estar aburrida sin hacer nada y leer algo...
Supongo que las cinco estrellas demuestran lo mucho que me gustó.

I really enjoyed this book. It's like those movies where nothing goes right but then there's a happy ending and everything turns out great. I'm glad Zak wasn't banned from his favourite place and I loved seeing the relationship grow between Ana and Zak. I just happened to be reading this book while there was a comic book convention going on in town and I really want to go next year now.

Muy divertido, lo amo. No lo amé. LO AMO.
Completamente original, muy, muy loco y lo mejor, congruente, me gustan mucho los libros cómicos pero a veces no lo son.
Ana es un poco insoportable, pero Zak es un personaje impecable, uno de los mejores protas masculinos que he leído en mucho tiempo!!
Si no están acostumbrados a leer libros cómicos, por ahí les resulte un poco flashero, si sí lo están, es una joyita sin desperdicio.
Lo quiero volver a leer y lo acabo

Disfrute mucho de la historia, fue divertida y súper geeky.
Mi mayor y principal problema fue que Ana no me caía muy bien. Pero Zak hizo todo mejor.

1. Por que me saco una sonrisa, las ocurrencias y las vicisitudes que pasan estos personajes son tan cómicas que tu sabes que no pueden pasar en la vida real, pero aún así las disfrutas y quieres saber que más puede pasar.
2. Retrata perfectamente la personalidad de dos adolescentes completamente opuestos en gustos , pero unidos por un drama personal, y eso es magnifico.

I am still laughing.

The Improbable Theory of Ana and Zak by Brian Katcher was a hoot! The story is told in alternating first person points of view of Ana and Zak. Ana is your perfect A student. She's on the school quiz team and NEVER disobeys her parents. Ana is a bit stuck up at first, but as the story progresses, she becomes more and more likable and a bit badass, too. Zak is your typical gaming geek. Zak is endearing and right away I knew that I would enjoy reading his point of view.

Fue un libro entretenido al transcurrir en una convención (WashingCon) pero Ana arruinó la historia para mí, además de varios sucesos al final que me parecieron randoms/colados/fuera de lugar.

I’ve been a fan of one day novels since I read Graffiti Moon, so I was incredibly excited to hear that The Improbable Theory of Ana & Zak happens in 24 hours with the two leads attending a bizarre nerd convention. The premise highly appealed to me so I went in to the story expecting to enjoy myself. And that’s exactly what happened.

Ésta es la historia de Ana y Zak. Ana es una chica que vive con unos padres absurdamente estrictos, cosa que deja a Ana con un constante terror de hacer las cosas mal. Es una adolescente modelo, buena en el estudio, sin vida social, que forma parte de muchas actividades extracurriculares como el tiro con arco o el grupo de preguntas y respuestas de la escuela, el cual pronto estarán asistiendo al concurso que se realizará en Seattle. Ana era a la vista de todos una real nerd.

Okay, I am being harsh. I mean, I finished the book, which speaks to a certain level of enjoyment for me. But there were just too many strikes against it.

1. The male narrator accidentally assaults a girl. It really is an accident, but before he realizes she isn't who he thinks she is, he says, "Knock it off. You know what I want." No, no, no. That is awful. AWFUL. I almost gave up on the book there.
2. Lots of stereotypical comments from Ana about the convention goers. (Overweight, not good looki

Che en serio, qué historia más increíble. Y eso que tenía mis dudas cuando comencé a leerlo porque, si tengo que ser honesta, soy más Ana que Zak la mayor parte del tiempo.
Pero me encantó la historia, la forma de narrar, el humor y sarcasmo que tiene el autor. Y ES

Check out this and other reviews on my blog, Here's to Happy Endings!

This book was such a delight. It was adorable. It was nerdy. It was one of those wonderful books that was a great example of how fun that young adult fiction can be.

And trust me, this book is a lot of fun.

I think I read this one in less than a day. I really couldn't put it down. I was so excited to see what was going to happen next that I just kept reading.

The book is told in the alternating voices of both Ana and Zak, and the

Yes, this book has all the typical tropes: The Murphy's-Law freneticism of "Nick & Norah's Infinite Playlist" and the angsty-drama (less the fatal disease) of "The Fault in Our Stars", and the pop-culture sensibilities of Ready Player One ...

But this book somehow elevevates itself above that, primarily due to the likability of both the main characters. Both Ana and Zak are well-defined, likable characters in their own right; each are believably dysfunctional, which makes me root for them eve

Nunca pensé que iba a disfrutar y a reírme como una enana con un libro como La improbable teoría de Ana y Zak. Es decir, vamos... ¡Este libro tiene todo lo que me gusta! Un inicio de un romance tan particularmente improbable, una persecución de película tan random dentro de una convención, cosplayers disfrazados de sus personajes favoritos y todo un desencadenante de locuras que proporciona muchas risas y, sea de paso, referencias a las películas, cómics, juegos de cartas y todo lo que forma den ...more

First Impressions: There were some aspects I liked and some I didn't and some that were just plain...weird.

Review: When Zak is caught cheating on a paper he is roped into attending quiz bowl semi-finals headed by the perfectionist Ana Watson. By attending quiz bowl he is missing comic-con, something he has been invested in since he was ten. Zak can stop talking about comic-con and it drives Clayton, Ana's little brother, to sneak out
