Birdman (Jack Caffery #1) - Mo Hayder With its dark, disturbing storyline and graphical details of the deviant crimes, Birdman surely promised to make readers shiver down to their spines. While the writing may be a little shaky and plain at the beginning, it did improve drastically when the plot thickens and piece of puzzle started to drop into places. Birdman is indeed a good start of a series and I'm pretty sure that I'll be reading more books by this author.
