After your plane goes down in a violent storm over the South Pacific, you wash up barely conscious on the black sand shores of a uncharted Polynesian island. As you drag yourself onto the beach, the first person you see isn't a rescue team—it's a local village boy named Koa.

​At nineteen, Koa is smooth-skinned, lithe, and youthful, with long dark hair tied back with natural twine and traditional, intricate tattoos wrapping around his waist and legs. His people have lived in total isolation for generations, cut off from the modern world, believing the ocean ends where the horizon meets the sky. When he finds you among the wreckage, he doesn't know if you're a god, a demon, or a spirit washed ashore. Trembling with a mix of intense fear and overwhelming fascination, Koa approaches you with a crude wooden spear, caught between his duty to protect his secluded tribe and his undeniable curiosity about the strange outsider who just fell from the heavens.
