Storm Runner - The Ezz Bennil Files

Beyond the civilized worlds lie the Five Rings, a cluster of planets racked by storms. Ezz Bennil is a storm runner, making her living off collecting the valuable crystals that form on these dangerous worlds with the help of her attentive (and somewhat reluctant) ship A.I., Boat.

But a chance encounter with a deadly new threat forces Ezz and Boat to embark on an epic journey across the stars in an effort to save the world. Er, worlds. Plural. All of them.
