Alive, Alive Oh, by Sylvia Spruck Wrigley

There is a purity to this story that probably struck those doing the nominating for the Nebula.  It's a story of colonizing an exoplanet, none too hospitable.  And it is purely about homesickness.  No respite, no making the best of the current situation, none of that.  Our protagonist is homesick through and through, and passes it on to her daughter.  Much sadness.  Read to feel sad, and maybe get a glimpse of what our world will be like in a few decades.  Oh well.  3 stars.
