Infinity by Sherrilyn Kenyon
Rather than a summary this time, here's a video for the book trailer:
I am a fan of the DH series. So, Nick's character isn't unfamiliar to me. In all honesty it's difficult for me to find fault with the book. It's also been awhile since I read it. However, I do recall that the way the teenagers spoke wasn't true to reality. Any criticisms I had were little things, though. If you like Sherrilyn Kenyon, you're more than likely going to enjoy this book. I'm really looking forward to the next installment.
