I almost gave up on this book, and I'm so glad I didn't. Gin Blanco is an assassin who goes by the name of Spider and was double crossed. She is out for revenge. Detective Caine Donovan is one of the good guys. Someone is out to get him, and the only way to find who is to work with Gin. Sparks fly, and the action never stops once it gets started. This is one book I'm glad I didn't abandon.
