Fire Song - Daughters of Avalon 4th edition

Praised for her beauty and grace, deep down, Seren Pendragon fears a rising tempest. Her mother is a witch, her four sisters are in peril, and she has been promised to a beast of a man who's already conspired against one king. When she and her youngest sister seize the opportunity for escape neither realizes how much their struggle will cost. Alas, it will take a terrible tragedy to unleash Seren's inner fire.

The Bastard Butcher of Warkworth is no stranger to misfortune. Everything he held dear vanished one night in a wisp of smoke, and he has been scarred by his encounters with Seren's mother, Morwen Pendragon--mentally and physically. Even so, when one of the Witch's daughters finds herself in trouble, Will must find the champion within and ride to her rescue.
