Katie Kim may be a newcomer to Camp Half-Blood, but even she knows they weren’t supposed to be running through the Wild Zone—the forest is off-limits to campers and staff. Why, then, did Clarisse, head counselor of the Ares cabin, take her and four other newbies there in the dark of night and tell them to race back to camp by morning? Clarisse’s threat was scary enough, but when Katie’s half-brother Grant goes missing, his disappearance sparks the arrival of vicious monsters and a mysterious curse. It’s up to Katie and the three remaining newbies—the Wild Omada—to brave the Wild Zone again and uncover its dark and deadly secrets.
