e-book from the Baen Free Library
Book 1 in the series: this is a re-read because I read book 1 then skipped to book 4. Now I'm going back to try to fill in the gaps but decided to revisit book 1 again first.
Owen Pitt is trying to be an ordinary accountant, even though he has a terrible boss. Really terrible: Owen's supervisor turns out to be a werewolf, and in order to survive, Owen ends up pushing him out of a 14th-floor window.
While this does mean he loses his job(!), he finds himself with another offer - from an organization called Monster Hunter International, headquartered in Cazador, Alabama.
MHI does pretty much exactly what you'd expect based on their name: they hunt inhuman monsters. These are the ones the federal government doesn't want the general population to know about - not ordinary criminals, but werewolves, vampires, and all sorts of other nasty creatures.
