The sequel to the Arthur C. Clarke Award shortlisted novel Edge of Heaven.

Luchtstad: the city in the sky. Beacon of hope. Place of refuge, of healing, of acceptance. At least, that's what the rumours say.

Reborn as Françoise Marechal, a-naut Danae Grant is trying to build a new life as a post-etheric citizen and to disappear back into the cracks. Nothing and nobody will ever touch her again. She's going to make sure of that.

Adam has been following a cold trail for the better part of three decades, ever since the love of his life was killed in the horrors that ended the a-naut Insurgency. He's looking for the only other survivor of their group - the one person left who can tell him what really happened that day. Twenty-five years on, the trail stops at Luchtstad. Adam's an older model and time is running out. This is his last chance to find the truth. In Danae, he sees a potential entry point into Luchtstad's secretive a-naut community. In Adam, Danae sees the threat that could end her carefully reconstructed existence. And the city has one more act of unimaginable violence to throw at them before their journey is done...

The truth, when it finds them, is something neither one of them could have guessed.
