A Time of Exile Katharine Kerr Bantam Books 1992
It is years since the half-elven Lord Rhodry took the throne of Aberwyn.
When Rhodry's lost lover, Jill-now a powerful wizard-comes to Aberyn and tells him it's time he accepted his elven heritage, Rhodry faces the most difficult choice of his life.
But with Jill's help and that of a human wizard named Aderyn who has lived for years in the westlands, Rhodry begins to understand how his life is connected not just to his own people, but to the Elcyion Lacar as well.
At last, destiny begins to unravel its secrets, revealing Aderyn's true purpose among the elves-and the god' deeper design behind Rhodry's dual heritage.
