Losing her magic was one thing, but getting bodyjacked by the ghost of her past self? That's a whole new low for teenage dream-weaving threadwitch Cole. And when sea monsters shipwreck her hard-won backup, there's only one hope left to contain the nightmares and escape a bodiless purgatory of eternal torment. But sacrificing the life of a child-however eerie and backstabbing-is too great a price to pay, even to save her friends and her city. As her remaining allies fall and resistance mounts, Cole fights to hold back the monsters at the cost of her own rapidly draining life force. In this explosive conclusion to the trilogy, the spark of revolution is lit-and even a drowned city can burn.
