Monster Island (Hardcover) (ISBN-13: 9780008473150)

First off, let's get one thing clear. Monsters under the bed are real.
Let me repeat.
MONSTERS UNDER THE BED ARE REAL...

Eleven-year-old Sam has been shipped off from her city home to the wild and windy Draymur Isle, where she lives in an old lighthouse with Granddad and his mischievous goat, Myrtle.

Not all is as it seems on Draymur Island, and Granddad keeps telling Sam to put jam on her feet before bedtime to keep the monsters away. Sam thinks he might be bonkers, but then she wakes to hear an odd squelching sound coming from under the bed...

Is it just Myrtle eating another one of Sam's socks? Or are Granddad's tales of mysterious monsters on the island true? Better get the jam, just in case!
