In the middle of a New York heatwave, the murder of real estate tycoon brings detective Nikki Heat to the case--and along with her comes the aggravating journalist Jameson Rook. Nikki Heat is hit with an unexpected challenge when the commissioner assigns superstar magazine journalist Jameson Rook to ride along with her to research an article on New York's Finest. Pulitzer Prize-winning Rook is as much a handful as he is handsome. His wise-cracking and meddling aren't her only problems. As she works to unravel the secrets of the murdered real estate tycoon, she must also confront the spark between them. The one called heat. Jameson Rook, is a fictionalized version of Richard Castle himself. If you watch the show "Castle" this will all make more sense.

About the Author
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 humor and inspiration."I do enjoy the way this series is being treated as a real thing and even has the actor "Nathan Fillion" who plays Castle as the author on the back of the book. I feel like ABC and the writers of the show are having a great time with this series and if you are a fan of the show then you'll enjoy these books.
