5 stars!! 
 I usually don't read standalone books just because if I like it, and finish it; I don't know what to do with my life, so that's why I prefer series. When I read That Thing Between Eli & Gwen , I wanted to reread it hundred times. It was such a refreshing, funny book that I needed at the moment. I was beyond surprised how much I loved the book and characters to be completely honest with you. 
 The book starts off with two individuals Eli & Gwen with their signification other. Gwen is at her house when her fiance picks her up, and she senses he's acting strange but doesn't think much of it. They end up reaching a wedding and then the story switches to Eli's POV, which ends up with Eli about to get married but in a matter of seconds, his fiance runs off with a stranger who we find out is Gwen's fiance. Both Eli & Gwen's fiances leave them standing at the wedding watching them run off with each other. 
 What I loved about this book is that the moment you start reading it captures your attention! I also love how J.J McAvoy made Eli and Gwen so different from each other and how they slowly started a relationship and that it wasn't one of those "love at first sight" or "rebound" type of relationships. It, in fact, was hatred at first but along the way they became friends which turned into more. I adore how they developed as people throughout the book as well. 
 I don't think that it's just a happily ever book because Gwen & Eli go through difficulties along mending their hearts plus trying to start a relationship with each other later in the book. 
 I recommend this book! Even though it's standalone and I don't know what I'm going to do without Eli's bossy grumpiness & Gwen's down to earth optimistic personality (they became one of my favorite couples) I'm just going to have to reread it multiple times until I can't anymore... oops.
