After the Buzzers' retreat from Heske, Earth Maneuver Forces believe they've cracked the code on where the insectoid aliens will strike next.

But when their forward deployment goes horribly wrong and nearly wipes out the advance force, the pressure mounts. With Earth's defenses stretched thin and Mars' forces barely regrouped, they're rushed to Trion 2—where they'll face not just the Buzzers, but something far more ominous.

Captain Mike Sandhurst's cavalry troop is slowly coming together as a cohesive unit, though internal challenges and the ever-present bureaucratic red tape of the larger military force remain a constant struggle. As he trains his young officers for the battles ahead, Mike also faces personal conflict—his growing relationship with Lieutenant Vivian Llewelyn. Vivian is back on Earth, recovering from her wounds and determined to return to flight status, even as her own challenges pile up.

Meanwhile, the Thunderbolts are putting the newly upgraded Osprey close air support aircraft through its paces. Faster, deadlier, and designed for brutal combat, the new airframes are powerful, but untested. With deployment looming, the question remains—will the new machines and their pilots be ready for the hell that's coming? Together, can the tankers and the aviators take the field?

The fight against the Buzzers rages in this new rollicking Science Fiction thrill ride from Kevin Ikenberry. With realistic military action, space and ground battles, and a vicious bug alien invasion, it's perfect for fans of Starship Troopers, Hell Divers 2, and Drop Trooper!
