I received this book as an ARC from Goodreads, and was really excited to read it. I thought it was going to be different, and I thought the cover was gorgeous. Unfortunately, I could barely finish this book. The first 130 pages or so, were completely boring. The Flash doesn't occur until after this, so those 130 pages are all about our main character, Evie, being the popular, rich girl going about her day to day life. Honestly, all of that could have been cut out, and summed up in a chapter or so. The "action" starts after those 130 pages, so I thought the story was going to get better, but it didn't. Not only was it more boring, but it was even more confusing. We never received an explanation as to why the Flash occurred, other than "the Sun." I'm sorry, but what kind of explanation is that? I need a little more. 
 Another problem I had with this book was the writing. I don't usually do background research on an author, so I assumed that this was a first-time author because that is how the writing appeared. I wouldn't have guessed that this was a seasoned author. Half the time, I didn't even understand what Evie's friend was saying. On top of that, there wasn't much set-up. This ties into the part after the Flash occurred. 
 However, my main problem with this book...the love interest, Jackson. I have never hated a love interest. Even when they were one of the bad guys that had the potential to turn into a love interest. But, Jackson was just insufferable. What is so appealing about a guy that drinks all the time (he carries a flask in his pocket), he was the biggest jerk, and there was no reason for Evie to be attracted to him-besides the fact that he was good looking. I was holding out hope that Evie wouldn't fall for him, but she does, and I honestly don't know why. Jackson had no redeeming qualities, and he was always trying to sleep with her. Really...he even says, "Hell, Evie, you're probably the last girl on earth for me. Would it kill you to put out?" When I read that, I was literally shocked. I mean seriously?! That's the guy you're going to fall for Evie? Have some sense! 
 I thought this book had so much potential. It was original and could have been great. However, to me it wasn't. I hate having to give bad reviews; I usually try to find something good in a book. But this book has nothing good. Perhaps to the right person, this book will be great, but I would say don't waste the time reading this book. It'll save you some frustration.
