The Sea of Storms — Mark Whiteway

On the planet Kelanni, life is cheap. With the aid of the fearsome "Keltar" enforcers in their flying cloaks, a ruthless invader is forcing the native people to mine the colloquially named "lodestone" - a substance from another universe with infinitely destructive power. The only ones who can stop him are a tiny girl with a fiery disposition, a former Keltar, a failed revolutionary, a musician and the mysterious creature, Boxx, who seems to speak only in riddles.
