A strange craft falls from the stars and crashes into the jungle near an isolated West African community. Inside, the locals discover the broken body of a man unlike any they have seen before – a man who is perhaps something more than human. His name is Samara and he speaks with terror of a place called Tartarus – an orbiting prison where hope doesn’t exist. As Samara begins to heal, he also transforms the lives his rescuers. But in so doing, he attracts the attention of a warlord whose gunmen now threaten the very existence of the villagers themselves – and the one, slim chance Samara has of finding his way home. And all the while, in the darkness above, waits the simmering fury at the heart of Tartarus . . .
