Highfire by Eoin Colfer

This is not a book for kids. But if you are in the mood for an adult story of a vodka swilling dragon, a corrupt sheriff and some good old boys on the bayou just trying to keep everything together, you are in for a treat. Vern has been hiding out in the middle of a podunk swamp island for a long time watching cable, drinking copious amounts of vodka and steering clear of the humans who just want to mess up his life. Along comes Squib who gets caught witnessing something that can mess up his life which results in an unlikely partnership. Now all they have to do is stay away from the law, drug kingpins, alligators, hogs and snakes. Bayou craziness that is just plain fun by the author who invented it.
