Extreme Threat (An Axel Strike Action Thriller—Book 3)

“Thriller writing at its best.” --Midwest Book Review (Any Means Necessary) ⭐⭐⭐⭐⭐

Former Airborne-turned-Homeland Security Agent Axel Strike is a special asset: he is only summoned as a last resort, when a crisis situation offers no other alternative but for an elite, daredevil agent to drop in from the sky.

In EXTREME THREAT (Book #3), when a ticking dirty bomb threatens San Francisco from within its tallest skyscraper, only Homeland Security Agent Axel Strike can infiltrate the fortress. Parachuting in from high above, Axel must navigate a maze of traps, outwit terrorists, and save hostages before the clock runs out on the city below.

EXTREME THREAT (Book #3) is the third book in an electrifying new action thriller series from the #1 bestselling and USA Today bestselling author Jack Mars (with over 10,000 five-star reviews). The series begins with EXTREME JUSTICE (Book #1).

The Axel Strike series delivers a riveting, adrenaline-fueled adventure brimming with surprising twists and exhilarating action that will hold you captive from the first page to the last. The compelling hero at the heart of this saga will keep you turning pages deep into the night. Fans of David Baldacci, Vince Flynn, and Lee Child are sure to fall in love.

Future books in the series are also available!
