Yvaíne has not returned to Spillwood since the village excommunicated him as a child. But when he finds one last opportunity to rescue his twin sibling from being sacrificed to the vampire lord in the old wood, he goes back a final time. But it’s not the old lord waiting for him--a vampire knight has arrived in Spillwood, and is demanding a tithe be sent to the capital, Hollowsorn, to dream-walk the Evensong and learn his secrets. Yvaíne will do anything to protect his sibling, including take their place as the human tithe—even if it means having to revisit the cursed magic that once lost him everything.
