A cutting edge space opera from the Hugo Award-winning author of SINGULARITY SKY. Freya Nakamachi-47 has some major existential issues. She's the perfect concubine, designed to please her human masters - hardwired to become aroused at the mere sight of a human male. There's just one problem: she came off the production line a year after the human species went extinct. Whatever else she may be, Freya Nakamachi-47 is gloriously obsolete. What's more, the rigid social hierarchy that has risen in the 200 years since the last human died, places beings such as Freya very near the bottom.
