The one thing that could save his life might also end the world.
When Charlie's called away from his history books to consult on a strange box at the museum, the last thing he expects to find is a cure for the disease that's killing him.
But nothing's that easy. It's 1915, the world's at war, and the same magic that can keep Charlie alive is being turned into a weapon in the wrong hands.
Charlie's caught in a desperate race to survive, keep his relationship with Henry a secret, and save the world from a mad wizard who just might make the Germans look good.
