About this book

Three new demigods—Jason, Piper, and Leo—are swept into a world where the Greek gods are real and monsters lurk around every corner. With Jason missing his memories, the friends must unite at Camp Half-Blood and set out on a dangerous cross-country quest to stop an ancient threat. The story blends fast-paced action, humor, and clever mythology twists that keep pages turning. Great for middle-grade readers who enjoy adventure and the Percy Jackson universe.
