Buried Deep: a Retrieval Artist novel by Kristine Kathryn Rusch

In 10 words or less: Skeletal remains on Mars threaten safety of solar system.

Review:
When a skeleton is uncovered on a construction site on Mars, medical examiner Sharon Scott-Olson is called upon to identify the body. More troubling is the fact that the Disty, the race of aliens that controls Mars, have severe cultural taboos regarding death. Anything or anyone that comes in contact with death is dealt with by the Disty Death Squads.
Nicolle DiRicci, newly named Chief of Moon Security, and her former partner, retrieval artist Miles Flint, join forces to prevent the Disty from causing widespread panic and death throughout the solar system.

Why bother? A blend of science fiction and mystery, this series would appeal to readers of J.D. Robb.
