The remnants of humanity reside on Mars after a nebulous Enemy destroyed Earth.

Revealed to be an advanced nanotechnological AI geared to produce paperclips, their Enemy does so with abandon out of everything it touches.

Taru, a recently-promoted cadet in the Martian special forces, is tasked to implement a mutually-assured destruction deterrent: to survive, the Martians threaten to destroy the Universe through false vacuum collapse if the AI attacks Mars.

As events around Taru escalate toward ultimate destruction, she will have to rely on the MAD game theory for humanity to survive.
