When a mysterious letter arrives during the summer holidays, Chris Spratt’s life is changed in a way he could never have imagined. Along with his friends Rosie, Ollie and Will, Chris has been given a place at the strange school of Cluifers, owned by the evil Dr Black.
When the friends discover that Dr Black has magically created the school to find a way to destroy them, they realise they must find the awful and long-hidden Spell of Whirldungen before Black can get his hands on it.
Accompanied by magical friends, shape-shifting moggy-cloggs, Chris’ genie and a talking book who knew Chris’ missing father, readers travel with Chris and his friends to the amazing Library of Leaves in the Academy of Mandria – a magical and, as it turns out, highly dangerous place. What with cloaks that can kill, gargoyles that come to life and a terrible spell to find, Chris and his friends are on a steep learning curve with no room for error. Who will get to the Spell of Whirldungen first?
