The genre of alternative history was once on the outer fringe of fiction, but has come into its own right in recent years. Some are very plausible, others totally fanciful, and many in between. Personally, I am a fan of the works that are plausible and stick very close to actual history except for that one fateful turn. The more fanciful works can be fun, I guess, but aren't nearly as stimulating, imho. How about you? Do you have any particular authors, books, or series you enjoy? Thanks.
