Mech Fighter Books in Order

After barely surviving an Exin attack, Dane Williams depends on experimental medication and a powerful robotic suit. Joining the Mechanized Infantry Division gives him a chance to fight the aliens while humanity faces the possibility of extinction.

Dane learns that human collaborators are aiding the Exin while a virus causes his nervous system to deteriorate. Leading a mission to protect key military figures puts his failing body and humanity's defense under pressure at the same time.

With humanity's defenses shattered, the Council of Worlds seeks peace with the Exin. Doubting that negotiations can save them, Dane Williams and the surviving metal warriors launch a desperate mission to end the alien threat directly.

Dane and his mech fighters discover a portal that could take the war beyond the solar system. Capturing it requires defeating overwhelming defenders, but controlling the passage could change humanity's ability to resist the Exin invasion.

Dane's mech fighters arrive on New Earth and discover that its exploratory expedition has disappeared. Searching for the missing scientists and comrades exposes them to relentless hostile forces, turning a hoped-for new beginning into a fight for survival.

After escaping the Exin Queen, Dane returns with intelligence that could help humanity fight back. A survivor found in an alien warship's wreckage offers another opportunity, but a changing battlefield puts the planned offensive in doubt.

Separated from his fellow metal warriors, Dane is imprisoned aboard an Exin mothership before reaching an unfamiliar world of enslaved creatures. Surviving captivity becomes bound up with escaping his confinement and freeing the planet's other prisoners.

Using ancient alien War Mechas, Dane attacks the communications network coordinating the Exin forces. The enemy launches its own offensive, leaving both sides damaged and the Mech Fighters struggling to prevent humanity’s destruction.

Dane and the Mechanized Infantry Division take their mech suits into space to strike the Exin before another attack on Earth. Intelligence supplied by an alien promises an advantage, but trusting it could lead them into a trap.
