- MICHAEL CONNELLY

It's elk season in the Rockies - but a different kind of hunter is stalking a different kind of prey.  Game wardens have found a man dead at a mountain camp - strung up, gutted, and flayed as if he were the elk he'd been pursuing.  A poker chip lies next to his body.  As ripples of horror spread through the community, Governor Rulon is forced to end hunting season early.  Are the murders the work of a deranged anti-hunting activist or of a lone psychopath with a personal vendetta?  Wyoming game warden Joe Pickett is the man to track the murderer down before someone declares open season on humans.

"Box ratchets up the suspense in this tightly plotted example of his writing genius."
- LIBRARY JOURNAL

"[Box] continues to be red-hot."
