I think that some books are more successful than others to certain readers. People who read my books for the humor, they're going to love one book. People who read my books for the mystery, they might not like that book quite as much.
Since I can barely write two books a year the best solution seems to be co-author projects. My goal isn't to get another writer to clone me... It's more to produce a book that shares my vision of positive, fun entertainment.
