The book centres on the fictitious President Jonathan Lincoln Duncan, determined to prevent terrorists from unleashing a cyberattack that could cause global devastation; to do so, he must go undercover, sneak out of the White House, and attempt to take matters into his own hands.

"I love thrillers," the former president added. "I read huge numbers of them. I've just finished the third book in the Red Sparrow trilogy [by Jason Matthews]." He also noted he was a particular fan of Patterson's, having "devoured" all 25 of the books in his Alex Cross series.
He added that he'd always wanted to write for himself, with this marking the first time a former US president has written a thriller.
Showtime has already acquired the rights to the novel with the intention to adapt it into a TV series, due to be broadcast next year.
