The Way to Rio Luna

Eleven-year-old Danny Monteverde believes in magic. He knows that pixie dust is real, that wardrobes act as portals, and that rabbit holes lead to Wonderland. Most of all, he believes that his older sister, Pili, is waiting for him somewhere in Rio Luna, the enchanted land in their favorite book of fairy tales.
Danny doesn't care what the adults say. He knows that Pili isn't another teen runaway. When the siblings were placed in separate foster homes, she promised that she'd come back for him, and they'd build a new life together in Rio Luna.
Yet as the years pass, Danny's faith begins to dim. But just when he thinks it might be time to put foolish fairy tales behind him, he finds a mysterious book in the library. It's a collection of stories that contain hints about how to reach another world. A map to Rio Luna... and to Pili.
As his adventure takes him from New York to Ecuador to Brazil, Danny learns that meeting your favorite characters isn't always a dream come true. But nothing will stop him from finding his sister... even if it means standing up to the greatest threat the magical realm has ever known.
