Sixteen-year-old Charlie Frith has problems. His crush is dating someone else, his sisters have glitter-bombed his prosthesis (again), and he's a seer-of-spirits in York, the most haunted city in England, and all his friends are ghosts.

Afterlives are at stake, and Charlie is running out of time ...
