Blood and silver

the long version

"Deacon Chalk normally has no trouble telling innocent victims from real monsters. So protecting an abused pregnant were-dog is a no-brainer...until a vicious lycanthrope leader and his brotherhood target Deacon, other shape-shifters, and any humans in their way. Suddenly, Deacon is outnumbered, outgunned, and unsure who - or what - to trust. The only edge he has left is a weapon hungry for his soul and his most savage impulses. And using it will exact a price even this hell-raising hunter fears to pay..."--Cover p. [4].
