The book I read was Elephant Run. In this book the main characters are Indaw, Jackson Freestone, Nick Freestone, Mya, and Hilltop. They all are living in Burma. One day the Japanese attacks! Everyone in Burma expected this to happen. The Japanese take everyone in Burma to different camps. Nick, Mya, and Hilltop are in the same camp. Jackson, and Indaw are in a different camp from Nick, Mya, and Hilltop. Hilltop knew of this secret place where they could escape and then save Jackson and Indaw. Hilltops plan was for him, Mya, and Nick to hide in the secret place for a long time. When the Japanese go into there rooms they will think that they had escaped. Once the Japanese called off the search for them Hilltop, Nick, and Mya would escape. So the next day Hilltop, Nick, and Mya did as Hilltop said. Once the Japanese called off the search they left! If you want to figure out if they end up saving Jackson and Indaw, or if the Japanese catch them, read Elephant Run.
