The Sheehy witches are the most feared and detested family on the island of Inisliath, and none more so than Rowan.

As a deathwalker, Rowan ferries island souls to the Otherworld, experiencing their deaths and carrying their memories like ghosts within him. It's a fated role he accepts even as it inexorably destroys him.

When the magic on the island starts to seep away from the other founding families, everyone blames the Sheehys?especially when islanders start dying.

Ash is sick of their father's fists and constantly having to apologize for who they are. Life on Inisliath might be the fresh start Ash and their mum need, and meeting soft-spoken, curly-haired Rowan feels like the ray of sunshine Ash has desperately needed?but everything goes sideways when Ash's mum becomes lead detective on a series of ritualistic murders allegedly tied to island magic, and Ash's family history.

The islanders are convinced Rowan is guilty, but Ash refuses to believe it. When Ash does some investigating of their own, they discover Rowan is far more likely to be the next victim. With time running out to save Rowan, Ash will have to choose between a life free of their father or the boy they're starting to love. Meanwhile Rowan will have to decide just how much he's willing to sacrifice to save his family from the darkness about to be unleashed on the island.
