An utterly gripping story of alien encounter and survival from Adrian Tchaikovsky, author of the Arthur C. Clarke Award-winning Children of Time.

They looked into the darkness and the darkness looked back . . .

New planets are fair game to asset strippers and interplanetary opportunists - and a commercial mission to a distant star system discovers a moon that is pitch black, but alive with radio activity. Its high-gravity, high-pressure, zero-oxygen environment is anathema to human life, but ripe for exploitation. They named it Shroud.

Under no circumstances should a human end up on Shroud's inhospitable surface. Except a catastrophic accident sees Juna Ceelander and Mai Ste Etienne doing just that. Forced to stage an emergency landing, in a small, barely adequate vehicle, they are unable to contact their ship and are running out of time. What follows is a gruelling journey across land, sea and air. During this time, Juna and Mai begin to understand Shroud's dominant species. It also begins to understand them . . .

If they escape Shroud, they'll face a crew only interested in profiteering from this extraordinary world. They'll somehow have to explain the impossible and translate the incredible. That is, if they make it back at all.
