Thank you NetGalley for providing an ARC in exchange for an honest review. 
 I received an eARC of this book 2 years ago, and this has been archived. I know it's pretty late but it's better that I've read this or else I will not be able to discover of how good this is. 
 One & Only is about Tess McMann. She's a simple, hardworking and an achiever. She got accepted on her father's alma mater, Canton University and wants to take bioengineering on the said university. However, her father wants her to attend a State university and take scholarships because the expenses at Canton is pretty expensive. The truth is, her father has another family. Tess and her mom lived in secret, and her father provides their needs. 
 After high school graduation, she attends a science camp at Cornell where she met Dylan Kingsley. He is a funny, dork but cute nerd. They have similar interests and soon became partners for a science project. During that camp, their feelings seemed to developed and hooked up.. Dylan is going to Canton University. However, she's not prepared to have a relationship with a boy who attends at Canton University. They lost their communication after she didn't replied on his messages, emails or returned his calls. 
 2 years later, Tess transferred to Canton University as a Bioengineering student. She sees the boy she fell in love with at Cornell. He's more handsome than she ever expected, it's just that he has a girlfriend. What complicates that? He is dating her half-sister, Hannah Swift. 
 I am instantly hooked with the story, the writing style and its conflict. I love the little drama. The romance between Tess and Dylan are so adorable in different ways. They're funny, cute, brainy and romantic. This book is totally a page turner. I swear it's really good. Dylan Kingsley is a Hot, Sexy, Nerd (with Glasses and sexy hair). Swoon worthy guy by the way. Gosh. Dream guy. HAHA! Tess is such a lucky gal. If you're looking a New Adult novel and you are in a reading slump, this book is worth the pick.
