Although the Rick Castle novels are actually written by a ghostwriter, the imprint takes a lot of trouble to keep up the fiction that Rick Castle had to follow around Kate Beckett for years so he would have inspiration for his character Nikki Heat.
Thats because Disney imprint Kingswell has signed on for two brand new books High Heat and Heat Storm that will be written by Rick Castle.
Castle may have aired its final episode on ABC, but the writings of Rick Castle will live on.
The books have Rick Castles name and image on the front and back covers and are essentially meant to go out into the universe as if they were written by Rick Castle.
