Marca Nbaro had always dreamed of serving aboard the Greatships, with their vast cargo holds and a crew that could fill a city.

They are the lifeblood of human-occupied space, transporting an unimaginable volume - and value - of goods from City, the greatest human orbital, all the way to Tradepoint at the other, to trade for xenoglas with an unknowable alien species.

And now, out in the darkness of space, something is targeting them.

Nbaro and her friends are close to locating their enemy, in this gripping sequel to the award-nominated Artifact Space, but they are running out of time - and their allies are running out of patience . . .

Written by one of the most exciting new voices in SF, this space thriller will keep readers on the edge of their seats.
