The Battle of the Labyrinth (Percy Jackson and the Olympians)

When Grace Cahill dies, her grandchildren, Amy and Dan, and seven other teams take up the challenge she left behind in her will: to search the globe for the 39 clues that will release the hidden power of the Cahills — a family filled with spies, scientists, artists and explorers — and make the winners the “richest, most important people in history.”

A cave monster … an abandoned demon … a ghost who wants to erase history … a killer commandant … These are just some of the challenges confronting the young heroes in this highly entertaining anthology. Ten bestselling and award-winning middle grade authors contributed to this collection: Roshani Chokshi, J.C. Cervantes, Yoon Ha Lee, Carlos Hernandez, Kwame Mbalia, Rebecca Roanhorse, Tehlor Kay Mejia, Sarwat Chadda, Graci Kim, and Rick Riordan, who also served as the editor.

Percy Jackson is a 21st century son of the ancient Greek god Poseidon on the biggest adventure of his young life — a quest to find out who stole Zeus’s lightening bolt! Together with his trusted friends, Percy travels through the United States, battling monsters and hunting the elusive title character.

Percy continues his epic adventures, this time he’s on the high seas and fighting to save Camp Half-Blood from monsters.

Kronos is at again and Olympus is threatened by an ancient monster. Percy and his friends must find the kidnapped Artemis — the only god who could hunt down the monster.
