★★★★ A SGT. MARVIN STYLES ASSIGNMENT SERIS: BOOK 3 NO MERCY GIVEN ★★★★

Still reeling from the loss of their president, Styles and his team dive headlong into the daunting task of tracking down the mastermind behind a perilous bio-weapon, touted as one of the most lethal synthetic toxins ever conceived, with the potential to decimate marine life. Guided by the relentless efforts of Darlene Phillips, their investigation unveils a chilling revelation: the adversary has his own tech savant, Alexi Zvonchenko, setting the stage for a high-stakes cyber showdown.

Their pursuit spans across Europe, culminating in Zurich, where they encounter Nicolas Emminger's impregnable digital fortress, guarded by Erma Hartmann, a former Olympic weightlifting champion. As they unravel Emminger's schemes, a startling revelation emerges—his involvement in the president's demise, intertwined with a newfound awareness of a clandestine sibling.

Meanwhile, a terrorist faction, the Caliphate Soldiers, emerges from North Africa, plotting a catastrophic attack on the Roman Coliseum. Amidst the chaos, an unexpected ally emerges to aid Styles in a pivotal moment.

Forced to divide their forces to address multiple threats simultaneously, Styles leads his team on a relentless pursuit across Europe and into the heart of Algeria, where the pursuit knows no bounds, and mercy is a luxury they cannot afford.
