Yoch

The only things Sydney Pointer knows about her dad come from the letters he sent her and articles published online about his daring life as a treasure-hunter. But now he's disappeared, and the only clue to what might have happened is a list of five stone talismans he gathered and hid for safekeeping. When Sydney is given the list, she knows it's up to her to find the stones and fulfill her father's mission to return them to the island temple where they belong.

The Time Stone is first on the list, but it isn't where it's supposed to be. Sydney and her friends must work together and follow a single clue to retrieve the stone and the clue to the location of the next stone before anyone finds out what they're up to and tries to stop them.
