The Greystone kids had the perfect life.
Then they discover three kids have been kidnapped. Kids with the same names, ages and birthdays as the Greystones!
When their mom disappears on a mysterious “work trip”, it’s clear not everything is as it seems.
Especially when a dangerous secret threatens to turn everything upside down.
The Greystones must follow a trail of clues, puzzles, and hidden codes to discover the real truth...before it's too late.
