Half the world is a wasteland: the other half is on borrowed time.

The West has been devastated by epidemics, bio-terrorism, war, and famine. Asia has shut its borders to keep the threats at bay, and some with power and influence have already abandoned Earth. Now an escape route a century in the making – the Nomad mission – finally offers hope to a small town and a secret research centre hidden in a rural American backwater.

Shrouded in lies and concealed even from the research centre's staff, Nomad is about to fulfil its long-dead founder's vision of preserving the best of humanity to forge a new future.

But who decides who's worthy?

The mission is now in the hands of a unique AI called Solomon, and an encounter with a band of military veterans reshapes his plans for mankind's future after the arrival of a scientist with a grudge threatens the whole mission.
