The worldwide bestselling continues with a brand-new adventure... and an even deadlier challenge.
The Vespers have crossed a line. Amy and Dan were devastated when the Vespers kidnapped seven Cahills around the world, holding them hostage until Amy and Dan delivered an impossible ransom. But at least the hostages were Cahills-members of the world's most powerful family, trained to face disaster.
But now the Vespers have kidnapped Atticus, an innocent 11-year-old boy and Dan's only friend. Dan and Amy find themselves in the struggle of their lives. Because if they can't outwit the Vespers, the unthinkable will happen...Atticus will die.
