Invasive

Once a dedicated pilot, Robin has one final job: to land a ship of pilgrims on a new world. There her husband can work as a botanist among people who share his faith, her kids can grow up in open spaces, and she can settle down to life as a full-time mom.
 

When she agreed to the idea, it didn't sound so bad. But now that she's pregnant with her third child and light years from home, things go sideways. 
 

The colonists' nature-worshipping religion hides a system of power and control. The planet was promised to be uninhabited, but something is stalking the colony from deep in the forest.  And the colony ship will never lift off again.
 

When Robin ventures into the forest to find out what threatens her people, she finds the line between peaceful pilgrims and rapacious invaders is thinner than she realized.
