Read Primal Storyline:

What if the worst happens and you are not a cop, or a spy with weapons
training and an iron heart? What if you're a schoolteacher - a mother?
In this gritty crime thriller a family vacation takes a vicious turn
when a fishing camp is invaded by four armed men. With nothing except
her brains, her will, and the element of surprise on her side, Alison
must kill or watch her family die. And then - things get worse.
