The Mystery of the Azure Star Publisher's Summary

The first exciting time travel adventure in the Time Sleuths series of mystery books for kids aged 8-12.

Thirteen-year-old Charlie Penrose and her ten-year-old twin siblings, Tom and Lucy, expect a sleepy summer at their Great-Uncle Bartleby’s seaside home. But then they stumble upon a golden pocket watch with a cryptic inscription, which hides a power none of them could have imagined.

With one press of a button the children are whisked back to 1965, and the fateful night the precious Azure Star vanished. What happened to the stolen sapphire has been a mystery for decades, and the Penroses have the chance to solve it! Yet snooping around the Swinging Sixties proves to be more dangerous than they expected. Secret passages, suspicious strangers, and a ruthless criminal soon have them in over their heads.

Can the Time Sleuths crack the case, find the stolen gem, and make it back to the present? Or will they find themselves stuck in the past forever?
