yep, there are a series of the 'Heat' books (and i think a 'Storm' book too) published by ABC Studios...that are 'written by' "Richard Castle - his picture is even on the back of the book (ok, its a pic of Nathan Fillion). there's been speculation as to who the actual author(s) is/are, but i think it was the tv show writers, actually
