Amateur detective Mallory Viridian's talent for solving murders ruined her life on Earth and drove her to live on an alien space station, but her problems still follow her in this witty, self-aware novel that puts a speculative spin on murder mysteries, from the Hugo-nominated author of Six Wakes.

From idyllic small towns to claustrophobic urban landscapes, Mallory Viridian is constantly embroiled in murder cases that only she has the insight to solve. But outside of a classic mystery novel, being surrounded by death doesn't make you a charming amateur detective, it makes you a suspect and a social pariah. So when Mallory gets the opportunity to take refuge on a sentient space station, she thinks she has the solution. Surely the murders will stop if her only company is alien beings. At first her new existence is peacefully quiet…and markedly devoid of homicide.

But when the station agrees to allow additional human guests, Mallory knows the break from her peculiar reality is over. After the first Earth shuttle arrives, and aliens and humans alike begin to die, the station is thrown into peril. Stuck smack-dab in the middle of an extraterrestrial whodunit, and wondering how in the world this keeps happening to her anyway, Mallory has to solve the crime-and fast-or the list of victims could grow to include everyone on board….
