Li-Zhen's life on the archipelago is simple. Known to friends and family as Lizzy, she takes care of her grandfather and their goats, she flirts with the woman who helps row the ferry, and she stays away from the fog that comes in the night-and the monsters hiding within it. But Lizzy's life comes apart when she steals a handful of coins from a sacred well to cover a debt. The well requires repayment, but it doesn't deal in coins. It needs wishes, and its minions will drown Lizzy in its depths if she doesn't grant them. Lizzy finds herself on a quest to uncover hidden memories, bestow great wealth, and face the magical secrets that nearly destroyed her family-and are now returning to threaten everything she has ever known.
