Day 115 on an Alien World by Jeannette Bedard

SPSFC

A barren world. A crashed colony ship. A saboteur at work. After a tarnished military record leaves her unable to find work on Earth, Margo is hunting for a fresh start. A colonizing mission heading to a new world creates the perfect opportunity—or at least that’s what she thinks. Strapped into a crashing colony ship, she realizes how wrong she is. On the ground of their destination planet, the straight forward colonizing mission becomes a scramble for survival. Her new world is harsh and unforgiving. Accidents keep happening. Too many to blame on bad luck alone. The trail of evidence leads Margo to a startling conclusion—one of her fellow colonists is a saboteur. Tomorrow is the colony’s first communications window with Earth and their only chance to send a message home. With the fate of the colony at stake, will Margo stop the saboteur before it’s too late?
