I have a box set of all the books in the series that's followed me around unread since ~1985. I don't remember why I have them, but all this time I thought they were some hard fantasy yarn based in some non-earth universe. By the mid 80's I'd kinda had my fill of fantasy after finishing the Thomas Covenant tomes, and couldn't care less if I'd never again bump into another hobbit, giant, orc, dragon, wizard or demented evil soul who's burning desire is to lay waste to the earth. I had no idea The Saga of the Exiles was about a bunch of time travellers and aliens set in the Pliocene era. I am definitely going to give this a shot now.
