About this book

This companion to the Percy Jackson and Heroes of Olympus series gathers four fast-paced adventures from the world of demigods, including a peek into Luke’s early days and new quests for Percy, Annabeth, and Leo. It blends humor, danger, and clever mythological twists in bite-size stories that are easy to pick up and hard to put down. Perfect for fans who want more Camp Half-Blood without a full-length novel, it deepens the world while staying light and fun. Great for grades 4–8 who enjoy Greek and Roman myths, snappy dialogue, and nonstop action.

Setting: contemporary United States and mythological realms tied to Camp Half-Blood and Camp Jupiter
