I finished this one a few days ago, and already finished book five too! This book was, to date, the most emotionally charged of the series. You are taken on an emotional roller coaster, as Ryder and Diana attempt to navigate through a turbulent patch in their unusual love affair.
Diana is realizing that her involvement with Ryder and his dark lifestyle is wearing down on the dreams she once had…a husband, children, and someone to grow old with. As the few years have progressed with Ryder, Diana feels her biological clock ticking, and she recognizes the call of “the darkness” growing within her. She both fears and is greatly attracted to Ryder’s dark side, and realizes that some distance from his world will be the only way she might truly find out what she wants in life.
