Science Fiction
At fifteen, Alexis Carew has to face an age-old problem - she's a girl, and only a boy can inherit the family's vast holdings. Her options are few. She must marry and watch a stranger run the lands, or become a penniless tenant. Yet there may be another option, one that involves becoming a midshipman on a shorthanded spaceship with no other women.
