This is Discidium: the separation of men and women as the final solution to the global population crisis that nearly destroyed humankind. To ensure this division, an impenetrable wall was constructed, dividing the two sexes into isolated provinces with little outside contact, ensuring fathers and daughters and mothers and sons would never know one another. Nearly one hundred years after its inception, Braedon Walker, devastated by the mysterious death of his father, defies the laws of Discidium and risks his life to meet a mother he's never known. At the same time, on the other side of the wall, Dr. Bo Granger, the daughter of ambitious and ruthless Governess Leda McCready, crosses a prohibited border into the integrated province of Conexus to investigate a series of inexplicable deaths in land of impoverished citizens. Aiding the two along the way are a series of eccentric and resourceful characters, including two criminal smugglers who prove to be much more than what they first appear. Braedon and Bo soon learn their individual journeys into the same forbidden territory are on a collision course, either towards complete disaster or profound revelation.
