The Heart of the Queen - Dragon Warriors, #3

The Darkness has come to Castle Linnivere. As the old enemy gathers strength, the Dragon Warriors desperately seek a way to halt its advance. But the true nature of the Darkness remains a mystery, and without that knowledge, the Warriors are blind.  Perhaps a solution can be found in the Gold Sea--the home of the Darkness itself--but only the strongest can survive the inhospitable desert. Or maybe the Warriors' best hope lies with the strange elven queen who arrives at the castle.
She may well hold the answers they're looking for . but can she be trusted?
