How do you protect yourself from a murderer on a planet that wants to kill you? In the four years between the arrival of the first team of colonizers on Mars and the landing of the second team, everything seems to have gone horribly awry. Five of the original colonists have become disillusioned with the mission and each other. The sixth original colonist is dead and it doesn't look like an accident. Now trapped on this planet and chained to the colony for life support, Sadie Blaine and her two teammates must solve the murder before the killer ends all life on Mars. Written in stages to mirror the multi-staged plans for colonizing Mars, First Grave on Mars begins the mystery continued in subsequent books. In this novella inspired by multiple companies’ plans to colonize Mars in real life, Veronica Brush creates the ultimate locked room mystery, where the suspects are the only eight people on the planet, and maybe Mars itself. First Grave on Mars is the debut novella and first in a series by the granddaughter of mystery author Joan Lowery Nixon.
