The last-known remnants of life from Upper World Earth is dying.

The underground city of Egerton’s population – saved from almost certain death on the surface 400 years ago – is shrinking.
Family Control Officer Aurora Cassle and Mayor’s Assistant Den Maron must find out why. Their investigation reveals Egerton’s long-forgotten history and long-buried secrets which generations of mayors have hidden from the public.

Den and Aurora’s research leads them to one conclusion; the only way to save their city – their people – is to return to the surface.
To do so presents great risk to everyone. No one can really predict what awaits them on the surface after four centuries – wars, disease, predators. Most are willing to take the risk, but some don’t want life in Egerton to change at all and do what they can to ensure no one leaves.

The fight to return to the surface comes at a cost no one expects.
