Subject: CAL

In a world where Earth is barren and only the rich thrive on lush, untouchable Mars, Calista Hartman was never meant to survive. As a baby, she was injected with Biosynth, an experimental serum that saved her life-but left her with abilities no one else has. To escape a fate of forced motherhood, she became Cal, a soldier hidden behind a man's name, fighting in a brutal society that sees women as nothing more than a means to repopulate.

For years, she's outsmarted them all. But when Cassian Thorne, a relentless officer, uncovers her secret, everything she's built is at risk. Now, as war brews between the dying Earth and the elite on Mars, Cal must make a choice: stay in the shadows, or rise and become the weapon she was never meant to be.
