Nikki Heat and Derrick Storm, New York Times bestselling author Richard Castle's most enduring and beloved characters, team up for the first time to save Nikki's mother, Cynthia, who has been in hiding (and presumed dead) for 17 years. Standing in their way is a nefarious group of Chinese businessmen known as the Shanghai Seven, who have the resources-and ruthlessness-to stop them.

Richard Castle is the author of numerous bestsellers, including the critically acclaimed Derrick Storm series. His first novel, In a Hail of Bullets, published while he was still in college, received the Nom DePlume Society's prestigious Tom Straw Award for Mystery Literature. Castle currently lives in Manhattan with his daughter and mother, both of whom infuse his life with humour and inspiration.
