Tangled up in swords, castles, and mists, Wyn's very essence is being ripped away by the spirit of Queen Guinevere. If she doesn't fight it, she'll be lost. But with every passing day, she feels trapped by desires she doesn't want, and it's getting harder to remember where she ends and Guinevere begins.
