ugh, cliffhanger! Yup, that's the first thought that came to mind when I finished Collide. Still, I'm not sure why we have a second book. Collide was long, too long, but with too much filler, that I think could have been left out and filled with more story. Instead of 2 books in the series, I think the author could have cut out some of the mundane and filled it with more Gavin and Emily. I know I am probably feeling this way because I am super frustrated with how this book ended (especially the last 15% that I saw coming but just wanted to pretend it wasn't going to happen). 
 Still, I gave this book four stars, and right now, I think it warrants that rating. The book was written well, the story was captivating and I cried on a number of occasions, which means it touched my heart. As many others who have read this book has said, this definitely reminded me of S.C. Stephens, Thoughtless. There was a love triangle and whole lot of angst, but the relationship between Emily and her boyfriend, Dillon was a he'll of a lot different from Kiera and Denny's relationship, which made the reader root for Gavin (the Kellan in this story) and Emily. That last scene with Dillon and Emily was brutal, and just reinforced my dislike for the Douche, as BFF Olivia liked to call him (the BFF always knows best!). 
 I feel like I was on an emotional rollercoaster with this one, and considering the teaser I read for Pulse (the second and final book in the series), I'm sure I'll be on another damn rollercoaster with that one, which obviously I can't wait for (but have to wait for till this summer). If I can give advice to anyone thinking about reading this one, all I can say is wait until Pulse comes out so you are not also dying with frustration, like me.
