Just finished reading. One of those books you pull all nighters to finish. The plot follows a couple humans thousands of years in the future, stranded on an alien world that is roughly in our middle ages. With a futuristic space ship racing to save them. Fun technology combinations of bows and arrows with ultra light speed travel and phasers.
Took off one star because I felt it dragged a little in the second half before the plot climax at the end.
Looking forward to starting Children of the Sky.
