The tenth and final book in the bestselling spy series!

When all of your family members are being kidnapped, how do you push aside your fear and discover what's happening before time runs out . . .

Someone has been plotting to bring down the Spencers ever since Kensy and Max were thrust into the secret world of Pharos, but they've always managed to stay one step ahead of their attackers . . . until now.

As members of the twins' inner circle - and Pharos's top agents - start to go missing, it quickly becomes clear that someone is staging a coup. Soon Kensy and Max are on their own, racing to get to the bottom of the terrible situation before the organisation completely falls apart. And before their family is gone forever.
