Nat Rodrigues keeps dreaming of an island. Soon, the dreams become waking visions. Alone and concerned, Nat manages to locate other teenagers across the globe who share her intense obsession with the unmapped enclave. And then, the strangest part: Every one of them wakes one morning with a mysterious tattoo. A tattoo only the six of them can see. Now, each of them knows—no matter the obstacles in their way—they must discover this unknown paradise.
After the destruction of their yacht, Nat and her misfit fellowship are stranded on the island of Oshtia. Worse, they’re obviously not alone. A mercenary by the name of Serena leads a group of modern day pirates who wish to plunder the magical paradise. As the group struggles to evade capture, they awaken ancient spirits that have laid dormant for hundreds of years.
