If my hair looks like bright green seaweed, it's because that's exactly what it is. My eyes, a pair of abalone shells, polished blue by sand. Teeth, two rows of pebbles. And my skin is made of wax.

Corpse never asked to be a kid ghost. She doesn't remember anything from her life - all she knows is her home on the rock-that-doesn't-exist, her friend Simon the spider, and the vile Witches whose magic she steals.

So, when she discovers that there's a powerful treasure which could give her all the answers to what she's lost - her memories, her family, her name - Corpse sets off to find it. On her journey across the stormy sea, she must battle magic, sea monsters and a cruel figure from her past. But the Witches want the treasure too. And they'll do anything to get it first.

A deliciously dark adventure, packed with chills, fizzing with magic and introducing a truly unforgettable heroine.
