Just binged this book in one day. 4.5 hours of audiobook this morning while at work, and then up till past midnight finishing it in e-reader format. 
 SO GOOD. I need to start the next book tomorrow. 
 Kyra wakes up one day behind a dumpster to find out that 5 years of her life have flown by. She's been missing (taken) this entire time and feels like not a day has passed. Five years ago feels like yesterday to Kyra. While everyone else around her has continued on with their lives though. 
 "Love required sacrifice and making hard choices and doing things that were bigger than just you. It wasn't something you asked for, or could control or change. It was something you accepted. Love was a force of nature." 
 The first half of the book was focused on building up the romance, settling back into life, and showing how difficult everything is now for Kyra. Once she learns more about herself, who she is, and what she can do the book REALLY gets going! Action packed, running, hiding, and super powers. Yeah - SUPER POWERS! 
 I can't wait to find out more about the fireflies.
