Heroes of Olympus (4): The House of Hades

Puffin Books

The Fourth Book in the bestselling spin off series from Percy Jackson and the Olympians, featuring the original hero – now in a brand-new look!

Lost in the depths of the Underworld, Percy and Annabeth's lives rest in the hands of their fellow demigods - Jason, Piper, Leo, Hazel and Frank.

Their five friends must reach the Doors of Death - gateway to the Underworld - if they ever want to see Percy and Annabeth again. But between them and the doors lies a vicious army hell-bent on destroying Camp Half-Blood. . . and the whole world with it.

If the demigods can fight their way through - and Percy and Annabeth can survive hell itself - they might just have a chance.

If they don't. . . Well, it's only the whole world at stake.
