Eva is a geek, a math loving geek whom even has a favourite calculator! She has been involved in helping out to tutor students. She is told by Josh, one of the popular school footballers, that she looks like a librarian with her glasses, but a cute one which boosts her low confidence. She has a serious issue with touching other people's belongings in an OCD behavioural way. But, she sees a pattern or a vision, a part of that person that isn't on show to the world, a secret. Both her parents are dead and so she has been raised by her mum's sister and pastor husband whilst they cope with quadruplets too.
Charlotte is her best friend and her opposite, tall, blonde and plays the cello.

Zenn, is a guy whom is struggling with math and is late when we originally meet him in the book, to meet up with Eva as she tutors struggling students and Zenn is new to the school.

Eva struggles with her college applications, she feels she should stay home and help with the kids but does want to study despite the huge debt. Charlotte fits in with the popular crowd after being asked to homecoming by Josh and subsequently she hangs out with Eva less too. Meanwhile, Eve starts to hang out in the art room and eat her lunch there with Zenn after he's done her family and church a favour. Zenn and Eva meet up and have their first kiss as well as Eva meeting Cinde, his mum.

As Eva grows closer to Zenn, she discovers the reasons to why she can't get any more visions/feelings when touching him or his clothing anymore, items around him that aren't his are still an issue though.

The surprise however, is a secret which drags up around eighteen years of history they never even knew they had between them both.

It was a gripping but heartwarming read dealing with love, loss and of course, proving even geeks fall in love when it's right. Many thanks to the publishers for allowing me to review this book for them!

Side note: I accidentally said Zenn diagram instead of Venn diagram to my A level maths teacher because of this book. It was incredibly embarrassing.

I don't usually like typical YA romance stories very much, but I quite liked this. It wasn't just romance, but that was quite a big part of the story.

Eva is eighteen and has never really been able to touch anyone or anything. Not because she can't, but because she gets serious fractals when she does. They're like visions, only made of just patterns and colour that show Eva the issues and problems people are hiding.

One good thing from these fractals is that they make her a great math tutor. Her maths skills are amazing, and when she touches anyone's calculator she can feel what math frustrations they have. Combining these two factors make Eva the best tutor, well, eva.

She has two students currently; Josh, the footballer and her best friend's crush, and the new kid, Zenn. Little does she know how both these boys are going to change her life...

Quick note: No, this is not one of those annoying love triangles.

Without giving too much away, it turns out that the circles of Eva and Zenn's life overlap more than they ever knew.

So the themes in this book are wide and plenty, ranging from religion to death of family, loss of virginity, first loves, best friends, and way more. I like how Eva is, at first, a very stereotypical nerd who finds most girls shallow and horrible, but that she allows herself to try makeup and become obsessed with a boy because she knows it's natural. Feminism should allow for love and crushes and makeup and girliness.

The writing is very appealing to the age group I think, the voice of Eva pretty accurate throughout the book. There is loads of humour, but also some pretty nice serious notes, too. The change brought on by her best friend beginning a relationship is very relatable, and well-portrayed. They drift apart, get new friends, but find their way back to each other eventually. It's quite sweet.

Eva's family is great, too. I won't ruin too much but her mother reacts so naturally to the circumstances.

My only real issue with this book is with the ending. I like that we don't know exactly what happens, but the whole deal with the scholarship/grant money... Hmm. Surely it would make Zenn angry to be treated like charity? And although it's nice, it's maybe a little too easy and perfect.

It was a really nice book. Not too long, but full of great content. Because of the ending, I will have to put my rating at 3.5 to 4 stars out of 5.

I'm sorry but I'm not interested in finishing this book, I realized Im not in the mood for this and after 35 pages of trying to read it I decided I didnt want to bother wasting my time if Im not interested. Nothing personal, just not what I was looking for.

This was a cute read! The main character got on my nerves at first, but eventually grew on me! It was a little predictable, but there was also some good humor!

i've been devouring YA romances like candy lately, and this one has been my favorite in a while. The characters were interesting and unique. The storyline had a sweet romance but was deeper than just that. Very enjoyable read!

Wait a second, as I wipe my tear...

This one just shot me right in the feels, and it gave me so much more than I expected.

Eva (Ev-ah) is a math genius with this mysterious psychic power, which makes touching people a very unpleasant experience. This inability to casually touch has left her with the label of a germaphobe and sort of isolated. Then she meets Zenn, and she finds that she would really like to touch somebody.

This book had just the right amount of weight. Although there were some very real issues addressed, they were not the main focus of the story. The story was about Zenn and Eva, and I was glad the author did not get sidetracked from this, because I loved their story.

Sidenote: My undergraduate degree is in Chemical Engineering and my graduate degree is in Science Education. The math geek in me was so delighted by this book. I mean, the math was strong.

"'Trig. Calculus.' I shrug. 'I'm kind of an all-around math slut.'"

"'Cosine,' I say, and start to copy a problem onto the paper. 'It's not just something your dad does on loans.'"

There are a lot of beautiful themes addressed here about forgiveness, sacrifice, family. It was very lovely and warmed my heart and all that other good stuff. I loved the twist, and I did not see this twist coming until Brant wanted me too (I think), and really liked how she tied it into other important parts of this story. (I know I am being vague, but I hate spoilers)

"Oh, lordy. He's using match analogies. I think I'm in love."

Most of all, I loved Eva and Zenn. Eva just jumped off the page. She was smart, funny, witty, awkward. She was someone I would want as my own friend. She was grateful for what she had, and willing to give up her time, money, and the things she may have wanted to let those she loved get what they desired. She did it for her parents, siblings, Zenn, and Charlotte. She was quite a special heroine. And Zenn. Zenn, Zenn, Zenn. He was so charming and sweet. He also had to sacrifice his wants and desires, because of his life situation. He was willing to earn his own way, and he did not want pity. Actually, these two characters had a quite a few similarities and were just perfect together.

"I think about when we met and I asked him his name and he made that Venn diagram with his hands. I probably fell in love with him right there on the sot. I think about how our circles once seemed to barely overlap. Two separate lives with a tiny sliver of math tutoring in common. But now it's like my whole circle and his whole circle are the same....."

And way to leave me with tears in my eyes and a huge smile on my face. That epilogue was everything.

Overall: a beautiful and moving story of love and sacrifice, that left me with a mile-wide smile.

The idea of Zenn Diagram was something that captivated me from the beginning. The whole aspect of Eva having visions when she touches people or their belongings makes for a great narrative and I liked how it all developed.

The falling in love, the secret, the fallout, everything was just the perfect romantic story. It was just too cute and sweet how the came to their feelings and what they are willing to give up for each other just solidified how amazing these two characters were for each other. I have to say I was very impressed by the plot twist toward the end, I was so not expecting that, so that made for even a greater story.

The reason I gave this book 3 stars out of 5 is just because there was some aspect of the book that I just couldn't be okay with. Some parts of the book felt a bit cliche and predictable. I don't really know what it was honestly, there was just something that just didn't click like I thought it would.

The story was good, the character development was good, the plot twist was awesome, something completely unexpected, but I don't know if it was the writing, the way Eva was just as a person or the fact that I didn't find out how she came to have the gift she has. Sometimes a book just doesn't click and I don't enjoy it as much as I originally thought I would. That's what made Zeen Diagram not the perfect book I was expecting.

Still I liked it, I would buy it and maybe read it later on and probably like it better. So I do recommend it, and I would encourage people to read it because it is a good story, it just wasn't the story for me.

This is a story that touched my heart, and made me like math! This story is about Eva a girl who is quirky, highly intelligent, and absolutely adores math. Eva has never been able to fall in love with a boy, as she feels awkward touching people or objects related to them due to strange occurrances that happen to her when she does. Eva's struggles with her inability to have human touch with others unfolds in the story in an intriguing and genuine way. There are layers upon layers to this story. Eva is both a beautiful and complex character. One day Eva meets a boy that will change everything and turns her world upside down. This is a beautiful, story about the power of love triumphing over all.

This was a DNF for me. The writing was awkward and the plot too everywhere to follow closely. I did love the characters tho so I was disappointed.
