The Barney for best cameo of Doc Holiday in a fantasy novel goes to…..
‘Territory’ by Emma Bull!
A really excellent historical fantasy novel that gives a new twist to the story of Tombstone, Arizona. With a little magic in the background, Wyatt Earp and Johnny Ringo work to extend their influence and power over the town. Throw in a couple of protagonists to root for, including a young reporter who secretly writes trashy serials, and you get a strange but fairly unique read.
