Maile Spencer leads the tour of a lifetime to Honolulu's fabled Iolani Palace. Even before she's off the tour bus, Maile is embroiled in a scheme to take over her beloved palace, and she has few places to turn for help. Going along for the scariest tour she's ever given is a group of Australian kids bringing a few troubles of their own. But it isn't her tour that causes problems that day, it's the unwelcome guests at the palace that threaten all of their lives. Go along with Maile and her group as they figure an escape plan from a building that has seen too much trouble, and has too many secrets that shouldn't be shared.
