This book is a collection of short stories about the adventures of Tarma and Kethry. They aren’t in anything like a chronological order, nor are they in order of publishing. Two of them, Turnabout and Keys, are almost exactly the same as chapters in “Oathbound”. Each of the stories has an introduction briefly laying out why Mercedes Lackey wrote the story.
All in all it is an enjoyable anthology. It’s pretty standard 80s and 90s fantasy stories, but they’re well written, engaging, and the characters don’t take themselves too seriously.
