As Summer slowly recovers from being savagely attacked and left for dead, it's not the assault that confounds her. As she, Templar Michael Charbon, and Wiccan Troy Atwater bond ever more tightly, their shared passion creates inexplicable changes in her. Though her two lovers vow to never again leave her unprotected, her unique power draws enemies to the Silver Wood Coven that none of them could have foreseen. Besieged from within and without, fractured relationships explode while damaged ones finally heal. As the winter solstice gathering draws closer, and the other covens converge, the stakes couldn't be higher. But when Summer's memories begin to return, she glimpses her terrible purpose. Not only will she need to summon her power and her courage, she must ask the ultimate of her two men.
