What’s it about?

The story.

Since her mum died, Gwen doesn't have time for feelings, not with two younger siblings to look after. When the family moves to their late grandmother's crumbling house on Gloam Island, everything feels wrong from the moment they arrive. Their new babysitter, Esme Laverne, seems sweet and kind, adored by everyone, but Gwen isn't fooled. She can see the monster behind the smile, even if no one else can. To protect her family, Gwen will have to face terrifying creatures and nightmares made real, and confront the grief she's been trying so hard to outrun. Jack Mackay's accomplished debut, with eerie chapter-head illustrations by Ben Joel Price, is a genuinely frightening but deeply felt horror story, praised by Lemony Snicket and Jonathan Stroud alike. Beneath the scares runs a tender, resonant story about loss, sibling love and the courage it takes to keep going.

Fit check

Right for your child?

Where it lands by age

For 9-12s reading independently who enjoy a genuine scare. The horror and a mother's death make it unsuitable for sensitive or younger readers or for bedtime, but its emotional depth rewards older middle-graders.

Why it lands

Why they love it.

Why kids love it

Gwen knows the sweet new babysitter is really a monster, and no one believes her. Kids love the creeping dread of Gloam Island, the nightmares that come to life, and rooting for a heroine who has to be brave enough to fight back alone.

  • Surviving danger
  • The underdog winning
  • Breaking the rules safely

Why parents love it

A confident debut that earns its Lemony Snicket and Jonathan Stroud praise: properly frightening, but underpinned by a tender story of grief and sibling love. It handles a mother's death with care while giving thrill-seeking readers genuine chills.
