My mind is blown! Full review to come :) 
 Update 7/21/13... 
 Holy mother of God!!! This book was amazing! Actually, amazing doesn't even cover it. If you love Daemon (which I and every other girl does), you will LOVE Hunter. Never has bad felt so right. Seriously. Hunter is not only muy caliente, but when we get to know him, he is a sweetie. But don't let that fool you...he's also a domineering, arrogant jerk (but that makes him all the better!!). This book, which to me is a spin-off of the Lux series, just for the adult world, introduces us to the world of Arum. While some Arum kill just for fun, most are out killing Luxen to protect and fight for their species. I loved the inside glimpse into the Arum world. In the Lux series, the Arum are shrouded in mystery, and it was nice to be introduced to their world. It is much different than I expected, especially the Arum's reasons for killing and going after the Luxen. However, just as with the Luxen, not all Arum are good and not all are bad. We find out a 
 TON 
 of new information that will be beneficial when reading the remaining books in the Lux series, however I definitely don't think a person would need to read this book in order to understand the remaining books. 
 The characters were superb. Granted, I got a little frustrated with Hunter at times, but that made him even better. You felt exactly what Serena, our lead female character and resident human, felt throughout the story. I loved Serena. While she was a bit scared in the beginning, and really who wouldn't be after witnessing your friend's murder and almost being murdered yourself, she grew into a headstrong, tough woman that wouldn't take no for an answer. Serena is also incredibly smart. I really appreciated that Serena didn't back down from Hunter. She wasn't scared of his true form, and she encouraged him to be himself and open up. Hunter is dangerous and tough as nails. He hates humans, but after meeting Serena, well...that attitude starts to change. His arrogance had me busting out laughing at times, but what I liked most was his growth and change over the novel. 
 Jen's writing is incredible as always, and there are some very steamy scenes in this novel. Overall, it was a great read, and while it would be better if you read the Lux series first, it's not necessary. This showcases Jen's amazing writing abilities, and I love how she opened our eyes to what the Arum are actually like. Throughout the Lux series, we are meant to hate the Arum and love the Luxen, however after reading this, we see a different side that is sure to change things in future novels. The best thing about this book....NO CLIFFHANGER!!! Jen, the master of the cliffhanger in my opinion, gave us absolutely no cliffhanger. Even though I would love another book about Hunter and Serena (and the Arum world), this is also a great ending that doesn't leave you on edge. So go and get this book now! You won't be disappointed!! Happy reading :)
