Tarragon Archer loves her job at the post office in Tombstone. All that mail coming and going is exciting, and she makes it a point to make sure she follows all the rules. Well, at least she tries to. When a new postmaster comes to town, she has a different idea about how how things should run, and Tarra doesn't like it. Will she be able to follow the new rules, or will she teach the new postmaster a thing or two about Tombstone...and love?
