The Ruins of Ambrai (Exiles, Vol. 1)

A thousand years ago, Mageborns fled prejudice and persecution to colonize the planet Lenfell--a perfect refuge for those whose powers were perceived as a threat by people not gifted with magic. But the greater the magic, the greater the peril. Lenfell was soon devastated by a war between rival Mageborn factions that polluted the land with Wild Magic and unleashed hideous specters called Wraithenbeasts. Now, generations later, someone is planning another war on the still crippled planet that will tear three Mageborn sisters apart.

Melanie Rawn has established beyond doubt that she is a great writer of fantasy and The Ruins of Ambrai will join the Dragon series in my library of favorites for years to come." --Realms of Fantasy
