Ever wonder what goes on at Camp Half-Blood in between Percy Jackson’s legendary quests? Find out in the start of a new series from #1 New York Times bestselling author Rick Riordan and an all-star team of coauthors! In book one, five newbie demigods dare to enter Camp Half-Blood’s forbidden Wild Zone, unleashing ancient curses, bloodthirsty monsters—and a fight to survive. 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.
