This is the perfect crime fiction with clones in space. Told with an economy of means at a galloping pace, it is impossible to put down. There is just enough world-building to get on with the story, and the diverse details we learn on the fly, from surprising turns of events and multiple flashbacks, all converge on the character-driven dénouement.
The novel constitutes a very interesting thought experiment concerning all the variations that cloning plus hacking (both genetic and psychic) can generate. The metaphysical theme of identity is cleverly inter-twined with the ethical theme of our responsibility for our unowned or unconscious past.
The style is flatly narrative rather than literary, but the intrigue and the suspense are very skilfully handled.
All in all not a ground-breaking work, but a quick and enjoyable read.
