With help from Mikkel Rasmussen (meaning, he did all the work), there is finally an e-book version of the Grim Fandango novel.
It's in the epub format, so it's compatible with any e-book reader that supports that format. For the others, calibre
should be able to convert it for your device. But remember, that's "should". And calibre is itself also a software e-book reader.
Below are direct links to the epub files. They are the same text, but formatted somewhat differently for different devices.
should work fine with most e-book readers and with calibre.
is tweaked to work with the Nook. (The difference being that the Nook requires, according to Mikkel, a flat directory structure. So if you have a Nook, or the first version just doesn't look right or work correctly, try this one.)
I should mention that the PDF version is still available at The DOD
although the epub text has been tweaked slightly to include fewer typos and more onions.
