Books like The Madness Season

For hundreds of years, Earth has suffered under the yoke of alien conquerors: the dreaded Tyr, a reptilian race in which all individuality is submerged into a single, overarching consciousness. Determined to keep humanity cowed, the Tyr have culled from the captive population the most intelligent, the most curious, the most likely to foment rebellion, and banished them from Earth. As the memory of freedom recedes, humanity sinks into a lethargic subservience. Daetrin, the hero of this tale, is a vampire--not a monster, however, but a man, nearly immortal, who embodies the vanished virtues of a once-sovereign Earth. When his existence is exposed by the Tyr, who are appalled to find a human who witnessed the Conquest, they immediately ship him offworld. Thus begins a journey of self-discovery as Daetrin is forced by adversity to come to grips with the long-suppressed side of his nature and to confront the ancient horror of a bloody heritage.
