From a random guest of the cluster worlds, Dana turns into the bride of the one who will unite nonhumans in the fight against monsters. In a matter of days, she and Amiar must face the ghosts of the past, find the missing lady of the trees, discover a spell that kills immortals, and restore the good name of a genius who for many years was considered a madman. They have devoted friends and newfound family on their side, but time for preparation is quickly running out - and the black dog Hades is already at the door.
