Randy Johnson posted on his blog about this book a couple of days ago and did such a sterling job of it, I'm going to suggest that you go over there and read what he had to say, if you haven't already. I'm just going to add that I think this is a fine novel, with plenty of history, humor, tragedy, and well-drawn characters. I met Jack McDevitt at an ArmadilloCon several years ago and thought he was a great guy. I've read three or four of his novels since then and liked all of them a lot. I don't think you can wrong with anything he's written. TIME TRAVELERS NEVER DIE gets a high recommendation from me.
