On a tiny island far away, in a sea that ripples with magic, Monty never knows what he might find …

Everyone loves Bring-and-Buy Day, when Trader Jolly visits the Island with all the supplies Monty and his friends need.

But this Bring-and-Buy day is different. Instead of Trader Jolly, there’s a sneaky new trader called Beady Bold. And he’s arrived with a boatload of trouble. The yum-yams are yummy, but they’re hiding a very scary secret.

All seems lost until Monty comes up with a daring plan.
