Two young sisters, Samantha (Sam) and Alexandra (Alex), get caught up in a war waged on another planet. Sam is picked to help Enella, a perture (a person and creature), fight evil on Enella's planet. Using skills learned from her dad, a combat veteran who was killed in action, and with the help of Alex and their pal Will, she takes on the evil force there. They are all shocked to learn what this evil force really is. Sam is smart with unrecognized leadership abilities. Alex is a bubbly girl with a distinctive sense of style but one of her best attributes is her PG skill-her Phoniness Gauge, an ability to assess people based on a phoniness scale. They are a formidable team. This story is one of confident, smart, and strong girls told with intrigue and depth. It is a study of character, loss, victory, and the importance of family.
