Space marines never say die.

Commander Andrew Ritchie swore a vow to exterminate the insect-like aliens that devastated humanity. But when his latest battle turns into a rescue mission, Andrew’s medical background draws the attention of a high-ranking officer—who reassigns him to the Valkyrie Corps.

This new medevac unit is a game changer, combining Andrew’s skills as a a medic and a combat marine. State-of-the-art Valkyrie power armor allows him to annihilate aliens while simultaneously saving human lives, giving earth’s forces a fighting chance against their ruthless enemy.

When Andrew’s team plunges into a hot zone of death and destruction, the secret behind the enemy’s carnage is brutally exposed. Andrew and his squad must now serve up a dose of vengeance.

Or else their next battle may be their last…
