“Thriller writing at its best.” --Midwest Book Review (Any Means Necessary) ⭐⭐⭐⭐⭐ LETHAL JUSTICE (Book #10) is the tenth book in a gripping 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 LETHAL FORCE (Book #1). Former Army Ranger and ex-NASCAR driver Derek Vesper is used to high velocity, whether its wheels, wings or skis. Assumed to be KIA in a firefight, Derek, unknown to anyone, uses his unique skills as a secret government operator to work outside the scope of protocol and to embrace the most dangerous—and fraught—of missions…. In LETHAL JUSTICE (Book #10), a doctor’s quantum encryption breakthrough has made her the most hunted scientist in Europe. Derek Vesper's cover as her elite chauffeur puts him behind the wheel of a seemingly ordinary luxury sedan hiding military-grade weaponry. When Barcelona's narrow medieval streets become a battleground, Vesper faces his ultimate driving test—a tactical duel with a ghost from his past. The Derek Vesper series delivers pulse-racing thrills and knife-edge suspense that seizes your attention with an iron grip. Featuring spectacular action sequences and mind-blowing twists, this series will propel you through a rollercoaster ride, from dynamite openings to jaw-dropping finales. Ideal for readers who love the works of Daniel Silva, Brad Taylor, and Vince Flynn. Future books in the series are also available! “Thriller enthusiasts who relish the precise execution of an international thriller, but who seek the psychological depth and believability of a protagonist who simultaneously fields professional and personal life challenges, will find this a gripping story that's hard to put down.” --Midwest Book Review, Diane Donovan (regarding Any Means Necessary) ⭐⭐⭐⭐⭐ “One of the best thrillers I have read this year.
