White Harbor War. Dana Valkyrie Adventures, #1

The Viking Maiden's crew has received some long-awaited shore leave and all Dana Valkyrie wants to do is kick her heels up, stay out of trouble, and devour the steaks and vegetables you just can't get in the middle of space. She might be the Maiden's champion, the best fighter on the toughest ship to sail the spaceways, but even Dana knows better than to pick a fight in a port as strict as White Harbor.
Her plans soon go awry when the local security division sends an agent to tail Dana through her shore leave, one of her subordinates proves determined to get into a brawl, and even her Captain volunteers Dana for a back dock MMA fight with the pride of the ship at stake. Dana knows the smart play is saying no, but as the stakes get higher and the Captain endangers the ship's very livelihood, Dana's got no choice but to put up her dukes and fight.
even if it means prison if they're caught. A science fiction MMA novella in the tradition of the great fighting stories of the pulp era, White Harbor War is the first entry in the ongoing saga of a two-fisted engineer, a mysterious Captain, and a crew full of trouble who take pride in being the toughest fighters in the universe.
