Mallory Vayle and Maggoty Skull are back and spookier than ever in... The Castle of Horrors, the third in the hilarious series for 9+ readers about a talkative skull and a necromancer-in-training.

When Mallory is invited to see Madame Majika de Vinckel's magic show, she rolls her eyes... Majika is bound to be a fraud, pretending to have powers she can't possibly have. But Majika appears to be the real deal, and she has good headdresses so of course Maggoty is an immediate fan.

Majika has a proposition for Mallory: help her open the Chest of Secrets and steal its contents, and in return she will help Mallory speak to her dead parents.

But can Mallory trust Majika? And what will happen if she steals what's inside the chest...

With the death-defying combination of Martin Howard's wicked humour and Pete Williamson's macabre illustrations, this series is not only the perfect Halloween treat but a side-splitting and spine-tingling year-round read.
