Read the prequel story, Alpha and Omega, in anthology ON THE PROWL before reading this book!!!!!! 
 The first time I read CW I hadn't read A&O in the anthology, and I felt like something was missing, something that stopped me from fully connecting with the characters. On my second read I read A&O first, and it really tied the story together for me. I understood the characters, their motivations and reactions better, and I made the connection with the characters. Reading A&O before CW makes for a more compelling, emotionally satisfying read. IMO. YMMV.
