Portland-area folks can find The Lure of Devouring Light at several Multnomah County library branches, according to this:

The Lure of Devouring Light at Mult.Co. Library

It may also be available from Clackamas and Washington and other county libraries, but I’m not a member of those so I’ll have to figure out how to check. If you happen to have a link to the book’s availability at your library, not just in the Portland area, let me know!
