In a creaky old house on a small, damp island, someone – or something – is waiting… 

Gwen doesn’t want to admit that everything feels wrong since her mum died. There’s no time for all these feelings now that she has her younger siblings to care for. Especially not since they've moved to their late grandmother’s house on Gloam Island.

 And now there’s an intruder. Esme Laverne may seem sweet and kind but Gwen isn't fooled by her new babysitter, even if everyone else is. It quickly becomes clear that if she wants Esme gone, she'll have to handle it herself. 

 Determined to protect her family, Gwen will have to fight off terrifying creatures and nightmares come to life. But as Esme’s power grows, Gwen must face everything she’s been running from and embrace her fears before she can defeat the monster in her home...for good. 

Not all monsters come out at night...
