Bring Me the Head of Ivy Pocket

Our magnificently infuriating heroine is on the very brink of her greatest adventure: bound for London and Prospa House to save Anastasia Radcliff and young Rebecca Butterfield from fates worse than death. But there are difficulties at every turn. The devious Miss Always and her devilish Locks are in hot pursuit. Anastasia is gone, taken by her evil sister-in-law Estelle and hidden in a place no one will ever find her. And worst of all, the Clock Diamond is no longer working, blocking Ivy's route to Prospa. There's a mystery to be unpicked and if anyone can do it, it's Ivy Pocket. After all, she has all the natural instincts of a Russian chess master.
Ivy Pocket's tumultuous finale is certain to involve breathtaking adventure, bone-shattering courage and frightful danger. But what price will she have to pay?
