Highfire

Vern is (probably) the last dragon alive, and is currently living a lonely life in the Louisiana swamp, until one day his covert existence is threatened by a teenager's run-in with a corrupt cop. Everett “Squib” Moreau manages to avoid incineration and convince Vern that he can be useful rather than a liability, but things get a little dicey when the corrupt cop keeps digging. Vern and Squib are forced into an unlikely partnership to save themselves and their loved ones.
Highfire is an entertaining adult fantasy novel with a quirky cast of characters. It is funny, sad, and graphically violent in equal measure. After a bit of a slow start the story picks up, with nonstop action towards the end.
