London, Heath Cranton / Maskew Miller, n.d. . First edition, first impression. Hardback. A very good copy. Colonial issue. A fairly unusual mixture of sf tropes including reincarnation, many worlds and apocalyptic destruction. In Blieler. Mason was a South African astronomer. The present title appears to be a simultaneous publication in London and Cape Town. The book's spine bears the name of both publishers, with the block being printed in the UK. No known priority between the UK issue and the Colonial issue. The jacket's a little worn and torn, with a couple of 25mm tears, some dints to the lower edge, some staining to the spine. A little bumping to the tips, but generally a nice copy. [10614, Hyraxia Books].
