About this book
After angering Zeus, the god Apollo is cast to Earth as a powerless teenager and must rely on modern demigods at Camp Half-Blood to survive. With his trademark wit and over-the-top confidence, he faces a mysterious enemy threatening the ancient Oracles. Fast-paced action, laugh-out-loud humor, and Greek mythology make this an easy hook for Percy Jackson fans. Great for middle-grade readers who enjoy quests, teamwork, and snappy narration.
Setting: present-day New York City and Camp Half-Blood (Long Island), with mythological locales
