"In the existence of our lives, there is a single coincidence that brings us together and for a moment, our hearts beat as one." 
 I read The Coincidence of Callie and Kayden when I was much younger and I LOVEEEEEED it. Even the parts I hated I loved. Well, Elisa, that doesn't make sense. Ugh, tell me about it. There are very, very few books that have this kind of effect on me. This one in particular made me go HOLY CRAP and DAMN and OH MY GOD every five seconds like I was a leaf at the wind's mercy. There was something so sweet yet brave about Callie. I liked her from the get-go, because you kind of get this impression of her that she's shy and weak and then BAAAM! she's all like I want to save Kayden from his asshole dad. 
 Kayden I thought was such a beautiful and strong soul. I just wanted to get in there and give them both a BIG hug. Like, SERIOUSLY, I want to be friends with these people. They had me right in the feels. I understood where they were coming from emotionally. To feel unworthy, like you're "damaged goods", but then have someone see you, truly understand you and accept you...well ain't that something? 
 "I can do pain. That's the easy part of life. It's everything else, happiness, laughter, love, that's fucking complicated." 
 Oh, and Seth is just ASFGHJKL. His and Callie's motivational list was a very nice touch. 
 READ IT. It's a fan-fucking-tastic read.
