The curious thing about this particular announcement, though, is that neither Deadly Storm nor Richard Castle exist in the real world: the author is the character played by Nathan Fillion on the TV series Castle, and Deadly Storm is part of his series of novels about action hero Derrick Storm (other volumes include Gathering Storm, Storm Season and Stormfall.
As it turns out, Deadly Storm won't be the first book to be published under Castle's name. Heat Wave and Naked Heat have appeared as prose novels in the past couple of years, and the latter hit #7 on the New York Times' hardcover bestseller list a few months ago. Deadly Storm will be "adapted"--from a nonexistent original!--by writers Brian Michael Bendis and Kelly Sue DeConnick, and artist Lan Medina. Its cover will apparently be shown on tonight's episode of Castle.
