Oh, how did I miss this when it first came out in paperback! This is a wonderful SF novel in the tradition I think of as cultural-anthropological SF. It was just re-released on e-book under the author's current writing name, Deborah J. Ross, but it's the same Northlight released in 1995 by Deborah Wheeler. I wanted to give you all a real review, because if you like my Nuala books, I think there's a good chance you'll enjoy Northlight.
If I was to sum this story up in one sentence, I would say that Northlight is a tale about the many forms of love, regret, and second chances.
Recognize that horse? It's one of Judith Tarr's Lipps!

Still not convinced?
( Here is a little more: )
You will not forget the POV characters, or the others who help and hinder them on their quest. And at $2.99 for the e-book over at Book View Cafe, this is a steal. Highly recommended!
