The Secret War

Grant Jackson, a former venture capitalist, thought he had left his past behind. But when Sir Geoffrey Gascoigne tasks him with stopping a Thule plot to assassinate the U.S. president, Grant is thrust back into covert operations. With the help of Jane, a self-aware AI, and the Mafia, he prevents the assassination-but that's just the beginning.
Grant's next mission takes him to the South Atlantic, where Thule aims to manipulate Argentina into invading the Falklands. With his new wife, Clara, by his side, he averts disaster, but they soon become entangled with the Italian N'drangheta. As Thule seeks to control the syndicate's business empire, Grant strikes a deadly bargain with a Libyan warlord to stop them.
When Islamic terrorists target Israel with a nuclear plot, Grant succeeds in thwarting them, but tragedy strikes when a bomb meant for him kills Clara instead. Devastated, he retreats to Morocco with his daughter, Sophie. Sir Geoffrey soon calls on Grant again, but grief weighs heavily on him. In the next book, an unexpected ally will help Grant find the strength to continue the fight.
