I just picked up a copy of Joe Haldeman's, "Forever Peace". I read "Forever War" when I was in public school back in 1976 and it blew my mind a little. I was 12 and the picture Mister Haldeman painted of warfare was memorable, detailed and gritty. The concept of time travel and relativity was new to me as was the concept of evolving human sexuality and trans-genderism. These were big concepts for a twelve year old, but they were the kind of ideas that stuck with me for decades. I still marvel at how prescient Joe was. The book is just as relevant now as it was then. I'm looking forward to reading Forever Peace.
