Black Sails to Sunward (en Inglés) - Sheila Jenné

In a world of frock coats, solar sails, and rigid class boundaries, a young Martian noble seeks her fortune as a midshipman of the Imperial Navy.

Mars and Earth are at war, and Lucy hopes for quick promotion. But when she arrives aboard ship, she finds harsh officers and a crew on the verge of mutiny. And worse: among the crew is her former friend, Moira-a commoner and a radical.

It's clear where Lucy's duty lies. As an officer and a gentlewoman, she has to quell the crew's rebellion and preserve her ship for the fight against Earth. But soon, she'll have to make a decision between all she's been taught to believe and the injustice she can see with her own eyes.
