An air force pararescueman and his son are on the run in William F. Sine's gripping debut novel, Tricklock. When Master Sergeant Jake Tricklock takes his adolescent son, Simon, on a wilderness camping trip, he has no idea that his heroic actions in the field will leave them fighting for their lives. But they must do just that when Khaled Ayoob, a rising al-Qaeda star, arrives with his team of killers to assassinate both Jake and Simon. Khaled hopes that by murdering them, he will ingratiate himself with a Taliban leader whose oldest son was killed by Jake during an attempted ambush in Afghanistan. This Taliban leader can then help Khaled carry out his ultimate mission: to launch a massive attack against American forces in Afghanistan-a spectacular exclamation point to Operation Powerful Vendetta that will forever cement his place as a terrorist mastermind. As the US sleeper cell is activated, Jake tries to bond with his son, who's more of a geek than a jock, in the Pecos Wilderness. It's up to the father-and-son duo to put aside their animosity and utilize their respective talents in an adrenaline-pumping test of cleverness and survival.
