'Find the thing the Witches call a treasure,' says Old Man, 'and you'll get back all those memories you're missing.'

With a body made of wax, seaweed for hair and polished abalone shells for eyes, Corpse is bound to haunt the Witches' sea shack forever. She has no memory of the kid she was before she was snatched and ended up on the rock that doesn't exist. But the delivery of an unexpected message sets Corpse off on a surprising quest, searching for answers to the old and familiar questions that have filled her not-brain since the day she first woke up a ghost. Questions about her name. Questions about her family.

With only her eight-legged friend Simon for company, Corpse heads into the unknown. There will be danger - cruel Witches, a silver-eyed sea monster and a cunning Merchant with a hungry grin - but Corpse is not afraid. She'll stop at nothing to uncover the truth about her past. Only it turns out that some answers are much closer than she thinks.
