So there's this writer, Barry Hughart.
And he writes these three terrific, virtually unclassifiable fantasies...think Sherlock Holmes meets The Sandman, set in Medieval China...and funny. In fact, he wins a World Fantasy Prize for The Chronicles of Master Li and Number Ten Ox.
But he and the publishers get into a big tiff and the series ends after three books, instead of the planned-for seven, and all the books disappear from view. Ten years after their original publication, an omnibus version went for $50 - if you could find it.
But now, thanks to ebooks and the Internet, Master Li and Number Ten Ox ride again! Hardcover omnibus, sure, for $40...but also as an ebook for $10. And you, lucky you, can buy the three books on Amazon or Barnes & Noble.
