For me, Alan Dean Foster is a very hit-and-miss kind of author. Some of his stuff--like this anthology--I really, really like. Other stuff is okay, and some stuff is just meh. But Mad Amos is easily my favorite book by him, and it's a setting I really wish he'd write more in. Frankly, it's a setting I wish more authors *period* would write in: the Fantasy West. This collection of tales reminds me--in a good way--of the tall tales of my childhood, such as Paul Bunyan or Johnny Appleseed or Pecos Bill. Mad Amos is quite at home amongst their ranks: a hairy, grizzly mountain man of uncertain age, uncertain lineage (he may or may not even be human), who rides a foul-tempered unicorn named Worthless (Amos keeps the unicorn's horn filed down and slaps a patch over it to keep it from growing back) and has a number of astonishing adventures across the Old West, ranging from the truth behind jackalopes (and what kind of animal hunts them)to a Chinese sorcerer and his dragon, to an actual kitchen-witch (no, not one of those thingies you hang on the pantry door). I can't help but feel (having read several ADF novels) that, like Orson Scott Card, Foster's talents as a writer truly shine more in short fiction than in novel-length format. But that is only my opinion, and regardless I recommend this excellent anthology.
I just wish we had *more* Mad Amos...
