In a creaky old house on a small, damp island, someone - or something - is waiting...

"Thrillingly scary and impossible to put down. Don't read it alone!" Jonathan Stroud, author of Lockwood & Co

A grieving family. A decaying house. A babysitter with a monstrous secret. Nothing on Gloam Island is quite what it seems...

Gwen doesn't need anyone to help her look after her younger siblings. And she isn't fooled by the beautiful babysitter with the hungry eyes and sharp teeth. But everyone else is. So if Gwen wants Esme Laverne gone, she'll have to handle it herself.

As Esme's power grows, Gwen must embrace her deepest fears before she can defeat the monster in her home for good.

Because as everyone knows, it's impossible to be brave unless you're already afraid.
