It was really refreshing to read a great adult paranormal book after such a long streak of YA. Don't get me wrong, I love YA, but every now and then I just have to get away from the teen angst and read about mature adults! This book definitely hit the spot. It was action-packed from the first page to the last. I loved the world that was built here. Dagan being a "soul-reaper" was a new concept for me and a great new paranormal type for me to love, and he was just uber-sexy. A compelling storyline that made me keep turning the pages late until the night. The mystery that unfolded throughout had me on the edge of my seat trying to figure out what has happened and what might happen next.The characters were great. Dagan was a strong, passionate male lead. He knew who he was and what he wanted and did whatever was necessary to make that happen. Roxy was my absolute favorite, she's smart--mouthed and edgy. A strong woman that is a rival for the most bulled-headed male, which I absolutely love. She's confused about what she is, but instead of sitting around whining about the cards that was dealt to her, she takes it all in stride and fights for the answers she wants.This was a great start to the series, great world-building that was revealed along with the action so that you weren't reading page upon page of it and getting bored. We're left with a cliff-hanger, but not one that's so bad it makes you want to smack the author, but definitely has you jonesing to pick up the next in the series. I recommend this one to any paranormal/urban fantasy fan! I can't wait to pick up the next Underkin novel and dive in!
