Molly of Mars in Pirra's World: Alien Revolt

In the exciting conclusion to the Pirra's World trilogy, Molly's success at the Sephian prison wasn't a win to her. Undaunted, she journeys across Sephia Prime with Vicky and Pirra. No matter the fear. No matter the cost. No matter what it takes, she will complete her most important mission. Anything short would mean death, or worse, torture for the rest of her life.
