This is a good story, novella. It follows Nerilka, one of the older fort hold daughters. She has always dreamed of visiting Ruatha hold. Lord Alessan's deceased wife had written her many times about life there. But when Ruatha has its first gather of the year, she is not allowed to go.
This is a follow-up to Moreta, as told from Nerilkas point of view. Hating that she's left behind, aggrieved that when her father jumps quarantine to return during the beginning of the plague, and then sneaks his girl, their children and her family to fort hold, but her mother and sisters are left to die. She decides she is not going to sit around, taking orders from a girl younger than herself.
Much of the story you will know if you've already read Moreta, but it's a good story by itself, just not as great as most of Anne McCaffreys books are.
