- New York : Scholastic, 2004.
- Children of the Red King .
The story begins when the magically "endowed" Charlie and his friend Emma discover a mostly invisible, strawberry jam-loving boy named Ollie Sparks imprisoned in the attic of the Hogwartsian Bloor's Academy. Ollie's plight is part of a seemingly amorphous Larger Evil Plot involving school authorities, a blue boa, and Charlie's three horrible great aunts. Charlie Bone and his friends are eager to fight wrongdoing with their combination of special powers, but obstacles in all shapes and sizes abound. Can the children rescue Ollie, Charlie's uncle, Ollie's older brother, and the other hapless victims...or are the enemies too plentiful and powerful?
