In 2142, women control human reproduction-and they're about to weaponize it.

Dart Maylord is a brilliant but isolated endocrinology researcher working for the Department of Reproduction in the female-ruled half of a divided America. She's never met a man, never questioned the wall that splits Washington, D.C., or the lies told about what stretches beyond it.

Until one day, a male researcher crosses that wall.

Alex Smern isn't the violent Neanderthal Dart was led to expect-he's sharp, disarmingly funny, and curious about the world she's never dared to question. Their collaboration begins with science but quickly becomes something more dangerous: connection. Trust. Desire.

Then Dart stumbles on a classified document she shouldn't see. The reproductive system isn't just being managed-it's being manipulated. And men are being systematically erased.

Worse still, Dart's own family may be orchestrating the scheme.

As she digs deeper, Dart must choose between protecting the people she loves and exposing a truth that could unravel the fragile balance of power. With Alex by her side and everything she thought she knew crumbling around her, Dart has to decide: is losing family worth rebellion?

Because if she doesn't act soon, there may be nothing left to save.
