More about The Crown of Ptolemy

Following a tip from Athena, demigods Percy and Annabeth travel to Governors Island in New York Harbor. A freak hurricane sends the mortals hurrying for the mainland, leaving Percy and Annabeth alone on the island.

Except they aren’t alone. The evil Egyptian magician named Setne is there, too, reading aloud from the Book of Thoth. They know he’s up to no good because . . . well, because he’s an evil magician. The fire-breathing snakes flying around him are a dead giveaway too.

Egyptian magic is more Carter and Sadie’s thing. Luckily, they show up in time to join forces with the demigods. With a little extra help from a vulture goddess, the foursome uses an unexpected and potentially life-threatening combination of Greek and Egyptian magic to defeat Setne. They trap the magician inside a snow globe. It’s the perfect prison . . . until the moment it isn’t.
