Son of Avonar — Carol Berg

Sorcerers are the stuff of legends, used as bogeymen to frighten children. Any magic has long been scoured from the Four Realms, and to be accused of associating with a suspected sorcerer means death--or worse....

Seri is a Leiran noblewoman living in exile. She wants nothing to do with the intrigues of her royal family, the politics of power, the unjust laws of her people. But her world is rent asunder when she shelters from Leiran soldiers a fugitive--a man with the skills of a warrior who is incapable of speech and quite possibly mad.

There is more to this stranger than meets the eye. And now Seri must help him remember who and what he is before those responsible for his condition find him...and unleash an apocalypse against the world.
