Raintree by Linda Howard

It's time to discover the Raintree trilogy

Two hundred years after the Raintree clan defeated and abandoned them on a small Caribbean Island, the Ansara wizards are rising again to take on their bitterest foes. Despite their extraordinary powers and supernatural origin, the Raintree have largely blended into the modern world. They are bankers, cops, husbands, wives and lovers in the society of humankind. But now, from Nevada to North Carolina, the rejoined battle will measure the endurance of their people. It will test their loyalties and relationships. And it will force upon them all new lives they could barely have imagined before.
