There's no such thing as escaping the Wildensterns . . .

It's been three years since Nathaniel Wildenstern left Ireland and his ruthless family behind. But no one turns his back on the Wildensterns, the powerful family controlling what was once the British Empire. While Nate's been gone, one of his maniacal cousins has been hard at work researching engimals--the bizarre living machines with the brains of animals--with the intent of creating the ultimate new species.

When Nate learns what his cousin has been up to, he knows he must return and put a stop to it. But in his absence, his clan has become even more despised for its merciless hunger for power. For Nate to succeed, he'll have to return in secret--because wherever the Wildensterns go, violence and betrayal are sure to follow.
