The Crown of Ptolemy

Trouble is brewing for Percy Jackson... An ancient Egyptian magician is back from the dead, experimenting with powerful magic and trying to become a god himself. It's more than Percy can handle alone - but when he teams up with Annabeth, Carter and Sadie, they find their usual weapons and spells aren't strong enough this time. Can they rise to the challenge and take down this wannabe god, before it's too late?
