I've been looking forward to Xypher's story since Kat & Sin's book and I was not disappointed with Dream Chaser. 
 Xypher is a dark soul and Simone is essentially his light, she gives him reason to go on. Simone is a strong and endearing character all on her own though. Kenyon weaves a sexy and exciting tale for these two that kept me on the edge of my seat and felt like a return to the original Dark-Hunter type of story-line. Loved!
