"I. AM. HOOKED! It is suspense and mystery driven, although as I said, the sexual tension is running high between Christian and Raven. I am looking forward to more of the story. Love, Love all of the team at Keystone.

"Dannika Dark remains the only author to give me cold chills while reading. Dark's writing was impeccable as is her usual, her characters were intricately depicted, and the mystery was good. The action had me on the edge of my seat."

"Each team member brings their own unique skill set to the team and without one, the others couldn't do everything that they do. I loved watching them work together and I really felt that they were a family. I will totally be reading more of the Crossbreed series. I enjoyed everything from the characters to the world and the story line."
