Slabscape: Dammit: Slabscape Book 2

Slabscape: Dammit is the second novel in the Slabscape series by S.Spencer Baker.
Somebody's slung a stop sign over a solar system and Slab is heading straight for it.
Stopping is not an option. Slab is over a thousand kilometres long, travelling at near-lightspeed and the thirty-two million humans, NAHs and avatars who inhabit the Slabscape are on a mission; they're going Home and wouldn't stop even if they could.
'The 'Slabscape' saga is a compulsive read for all those with a vivid imagination, a strange sense of humour and a passion for sci-fi.'

'The best deep space/far future sci-fi this side of Iain M Banks and Alistair Reynolds.'
