Highfire by Eoin Colfer

In the days of yore, he flew the skies and scorched angry mobs'now he hides from swamp tour boats and rises only with the greatest reluctance from his Laz-Z-Boy recliner. Laying low in the bayou, this once-magnificent fire breather has been reduced to lighting Marlboros with nose sparks, swilling Absolut in a Flashdance T-shirt, and binging Netflix in a fishing shack. For centuries, he struck fear in hearts far and wide as Wyvern, Lord Highfire of the Highfire Eyrie'now he goes by Vern. However...he has survived, unlike the rest. He is the last of his kind, the last dragon. Still, no amount of vodka can drown the loneliness in his molten core. Vern's glory days are long gone. Or are they?

A canny Cajun swamp rat, young Everett 'squib' Moreau does what he can to survive, trying not to break the heart of his saintly single mother. He's finally decided to work for a shady smuggler'but on his first night, he witnesses his boss murdered by a crooked constable.

Regence Hooke is not just a dirty cop, he's a despicable human being'who happens to want Squib's momma in the worst way. When Hooke goes after his hidden witness with a grenade launcher, Squib finds himself airlifted from certain death by'a dragon?

The swamp can make strange bedfellows, and rather than be fried alive so the dragon can keep his secret, Squib strikes a deal with the scaly apex predator. He can act as his go-between (aka familiar)'fetch his vodka, keep him company, etc.'in exchange for protection from Hooke. Soon the three of them are careening headlong toward a combustible confrontation. There's about to be a fiery reckoning, in which either dragons finally go extinct'or Vern's glory days are back.
