What this book is about
Jason Grace has no memory of who he is. Alongside Leo Valdez and Piper McLean, he discovers he's a demigod caught between Greek and Roman mythology. To save Hera—and prevent the Giants from waking—the trio must complete an impossible quest. The Lost Hero launches The Heroes of Olympus with a new trio, a broader mythology, and the mystery of Jason's lost identity.
