Blurb

The Beast Master is a science fiction novel by Andre Norton published by Harcourt in 1959. It inaugurated the Beast Master series, or Hosteen Storm series after the main character. In German-language translation it was published as Der Letzte der Navajos —literally The Last of the Navajo.
Norton wrote one sequel published in 1962 and three by Andre Norton and Lyn McConchie of New Zealand were published forty years later, one of them after Norton's 2005 death. According to McConchie, they were "written solely by Lyn from a brief collaborated outline." The first two latterday sequels were named the year's best novel by New Zealand science fiction fans.
