Regrettably, I downloaded this book before looking at the string of reviews and comments associated with this publications.  It is a pity that there is copyright infringement and that corporations like Amazon have gotten into bed with companies that promote piracy.  With that said, I must admit that I enjoyed the book.  I am a long time fan of Poul Andersons Time Patrol series and his novella High Crusades.  When I saw this book listed in Kindle format, I jumped for it.  While the stories are slightly dated, they are still enjoyable to read and are interesting.  I highly recommend if you can find a legitimate copy of any of these stories, download it and read it.  Im certain that you will enjoy it.
