In this third magnificent adventure for Martha Grimstone, Martha decides to use her fledgling magic to control a whirlwind, but she ends up with too many rabbits instead. Can she find a way to turn the rabbit fur into something useful?

Hello, I'm Martha Grimstone, and I've inherited my father's gift for music. I can play notes that will bring sunshine, breezes and rain, and send clouds scudding across the sky. But I can't turn back a storm.

If only I can convince Grandpa Grimstone that I can be trusted to leave the valley, I know just the place where I can learn more - but after my latest catastrophe there seems little hope of that. Perhaps Tillipilli and Ziphwort will help me...

The Grimstones: Whirlwind is a gothic fairytale about a whirlwind that refuses to be stomped on, two feisty Angora rabbits, and a disaster of exponential proportions that could be woven into something magnificent.
