Set in the unique world first featured in the award-winning Light, here is a story of love, murder, and intergalactic noir on the razor’s edge of the imagination, as envisioned by the incomparable M. John Harrison.

Not far from Moneytown, in a neighborhood of underground clubs, body-modification chop shops, adolescent contract killers, and sexy streetwalking Monas, you’ll find the Saudade Event Site: a zone of strange geography, twisted physics, and frightening psychic onslaughts. Vic Serotonin is an illegal “travel agent” into and out of Saudade. His latest client is a woman as unpredictable as the site itself—and maybe as dangerous. She wants a tour inside Saudade just as a troubling new class of biological artifacts have started leaving—living algorithms that are transforming the “real” world in unsettling ways. Pursued by a detective intent on collaring him for his illegal tours, and hunted by a gangster convinced that the travel agent has infected him with a rogue artifact, Vic must make one final trip as the universe around him rapidly veers toward viral chaos.
