What it argues
On a hot June night in Vermont, twelve-year-old Lisa vanishes into the woods behind her family's house. She had told her younger brother Sam she was going to meet the king of the fairies. Fifteen years later, Sam and his girlfriend Phoebe begin receiving strange messages that suggest Lisa may still be alive — and that someone, or something, has been watching them all along.
McMahon braids two timelines — the summer of Lisa's disappearance and the present — to build a mystery that sits at the edge of magical realism and psychological horror. The central question isn't just what happened to Lisa but whether the fairy world she believed in was real, metaphor, or the invention of a deeply troubled mind. The novel is genuinely interested in the way children construct belief systems to survive difficult circumstances, and in how those systems can calcify into something dangerous.
What it gets right
- 1.
The fairy mythology Lisa constructs is a survival mechanism — a way of framing powerlessness as a secret, chosen identity rather than victimhood.
- 2.
Memory is shown to be unreliable not just incidentally but structurally. The dual timeline makes readers complicit in misreading the past.
- 3.
The novel argues that secrets shared between siblings become their own kind of covenant, with costs that persist long after the original event.
