Charlie Bone and the Invisible Boy

The story centers on a "ghostly" mystery: the discovery of Ollie Sparks, a boy who was turned invisible by a blue boa constrictor and has been living, unseen and forgotten, in the attics of Bloor’s Academy for years. Charlie and his friends must find a way to make Ollie visible again before he fades away forever. Meanwhile, the "possessive" and manipulative Yewbeam aunts are ramping up their control, and a new student with the power to "charm" others into submission creates an atmosphere of psychological entrapment.
