Danny and Elena are now working for the Firm, desperately attempting to track down the vengeance-seeking Black Star before more 'Angels of Death' suicide bombers are despatched.
Elena is the key to discovering the bomb-master's whereabouts as she has already made Deep Web contact.
The plan is simple - locate Black Star and kill him - at whatever cost.
While Fergus is forced to remain in England, confined to a wheelchair as he recovers from his injuries, the hunt takes Danny and Elena to New York on a covert mission led by Marcie Deveraux. Despite Black Star's trickery and deception, the net gradually closes.
Fergus travels to the US to help, but Elena is drawn into terrible danger, and only Danny can save her.
Using the skills his grandfather has taught him and his own initiative, he must stop the avenging bomb-master from wreaking further destruction . . .
