Stanford Samuels is an ordinary man with an extraordinary disease, segregated with his fellow mutants from the healthy population by eighty-foot walls. Sarah is the genetically perfect woman assigned to eradicate his mutation and deliver their family to safety. Only those who contribute a healthy offspring to the population will be granted entrance into the dome.

“The way to salvation is through the self-sustained bio-dome, free of the ills that have nipped at the heels of mankind throughout history. The artificial environment under the dome will offer all that we consider good – fresh water, fertile land, minerals for mining – without the disease and rot that has plagued us until now. The new society will exist not in sickness but in health …”

In the distant future, planets in the explored galaxies have been plundered and left uninhabitable. The search for alternatives is now exhausted, leaving the only option for colonization on a planet whose twin suns are moving rapidly towards extinction. To ensure the long-term survival of mankind, a massive bio-dome is being constructed to house the population after permanent midnight – but not everybody is welcome. All known genetic diseases have been banned to protect the delicate ecosystem inside the artificial environment. All Stanford needs to do to book his family’s ticket to the dome is bear a healthy offspring with Sarah. But fertility is never guaranteed, not even for a perfect couplet, and with civil strife trumped only by the impending threat of perpetual darkness, Stanford must defy his own moral compass as he searches for truth along Idyllic Avenue.
