“The perfect series for fans of Rick Riordan’s Percy Jackson and the Olympians books.” —School Library Journal

All three books in the middle grade Cronus Chronicles series, inspired by Greek mythology and perfect for fans of Percy Jackson, available together in one collectible paperback boxed set—now with a new look!

Something extraordinary is about to happen to Charlotte Mielswetski. Oh, it’s not the cute kitten that appears out of nowhere. It’s not the sudden arrival of her cousin Zee, who believes he’s the cause of a mysterious sickness that struck his friends in England. And it’s not the men in tuxedos who follow Charlotte everywhere.

What’s so extraordinary is not any one of these things. It’s all of them. And when Charlotte’s friends also fall sick, Charlotte and Zee set out on a quest to find a cure that leads them to the Underworld. Once there, they discover that the fate of every person—living and dead—is in their hands.

After emerging victorious, Charlotte and Zee attract the attention of more dangerous adversaries, including the god of the sea and an ancient brotherhood. Armed with nothing but their friendship and wit, the cousins fight earthly and mythical threats alike to keep them from destroying the world.

This action-packed paperback boxed set includes:
The Shadow Thieves
The Siren Song
The Immortal Fire
