The Rage

The Rage is the first book in The Year of Rogue Dragons trilogy by Richard Lee Byers.

"Renegade dragon hunter Dorn hates dragons with a passion few can believe, let alone match. He has devoted his entire life—a life spent in the twisted body of a half-golem—to killing every dragon he can find.

You might feel the same way if one of them had killed your entire family in front of your eyes, bitten you in half, and left you for dead.

Killing one dragon at a time is hard enough but when the irresistible impulse to slip into feral madness begins to overcome not one, but every dragon all across Faerûn, civilization's only hope may lie in the last alliance Dorn and his fellow dragon hunters would ever accept.

No matter what happens, the next year is going to be a difficult one for Dorn, and for Faerûn itself.

The Year of Rogue Dragons has come."
