The Four Horsemen have turned space into their private empire. These trillionaire moguls operate beyond Earth's laws, building everything from orbital stations staffed entirely by women to lunar monasteries to massive solar shades designed to cool the planet. Their most ambitious project yet threatens to reshape humanity's future entirely. Earth's governments respond by deploying an elite team of military women who masquerade as ordinary space colonists. Their mission is to infiltrate and destroy the billionaires' most dangerous venture. But the women discover that nothing unfolds simply when vast wealth controls the cosmos. From space stations to Moon bases to Mars, the conflict escalates across the solar system. Each side believes they fight for humanity's survival, yet both may be wrong about what that actually requires.
