Camp Half-Blood by Rick Riordan, Annabelle Oh (Signed!)

DISCOVER WHAT IT MEANS TO BECOME A HERO IN THIS NEW SERIES SET IN THE BESTSELLING WORLD OF PERCY JACKSON!

From #1 New York Times bestselling author Rick Riordan and co-author Annabelle Oh comes book one set at Camp Half-Blood. Five newbie demigods dare to enter the forbidden Wild Zone, unleashing ancient curses, bloodthirsty monsters—and a fight to survive.

The hardcover edition features a unique stamp of the Camp Half-Blood logo, plus lush endpapers that display Katie Kim's impressive grid-mapping skills and a map of Camp Half-Blood in more detail than ever!

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.
