Welcome to Keldur, as Yuletide approaches, the island of Keldur prepares for twelve days of celebration, tradition, and winter magic. But this year, the Chief's daughter, Greta, faces a future she never wanted: marriage. Unless she chooses a husband before the winter solstice, her fate will be decided by the winner of five dangerous trials devised by the council.

As fierce warriors compete, an even greater mystery begins to unfold. The island's dragons have produced fewer hatchlings with each passing year, and the appearance of a rare dragon egg during the Yuletide festivities could change Keldur forever.
