Earlier this year, HarperCollins Publishers offered Neil Gaiman‘s American Gods for free online for a month.

This experiment apparently was a great success, because now the publisher is offering another Gaiman title, Neverwhere, for free until September 23, 2008. Visit HP’s Neverwhere page to read it online or download a free copy of the book.

According to Gaiman’s official site, in order to download and open the PDF you must have Adobe Reader 6, Adobe Reader 7, or Adobe Digital Editions installed. The default PDF reader for the Mac will not be able to open it. Linux is right out. No other work-around should be necessary.
