The Far Rings

At the tail end of a galactic war, Athena, a humanitarian medic, finds herself alone on a transport ship with a dashing captain she might remember from a distant past and an alien war criminal who doesn't quite look the part. In three days, their ship will reach the planet she used to call home, but perhaps Athena must choose a new future, and may even find love, from the struggles she and her two companions will encounter.
