The Cuckoo’s Calling By Robert Galbraith aka J.K. Rowling
The author, known for the Harry Potter series and writing this under a pseudonym, creates an interesting protagonist, Cormoran Strike, a down-at-the heels P.I. trying to stay alive. He is the illegitimate son of a rock star brought up by an unusual mother, who found a home in the British army until he lost a leg in Afghanistan. It yet remains to
be seen whether he can (or will) be more fully developed as a character in the future, since he really is two-dimensional in this novel.
