Just when Amy and Dan Cahill think their family is safe, disaster strikes—seven Cahills are kidnapped by a shadowy group known only as the Vespers.

But even as the race to save the hostages begins, a sinister question looms: What are the Vespers really after?
With the lives of their kidnapped relatives on the line, Amy and Dan are given another impossible request—steal a priceless map that's been missing for more than half a century.

The Vespers capture a blameless bystander—Dan's best friend Atticus.

If he doesn't, his best friend will surely die.

There's a Vesper mole in their inner circle. Vesper One's next assignment will take the Cahills somewhere crawling with dangerous enemies. They have just days to complete their next assignment and discover who has their back... and who wants to stick a knife into it.
