I heard of Martin Millar from Neil Gaiman's blog. Neil Gaiman praised Martin Millar's wisdom, wit and solid writing in "The Good Fairies of New York" -- and mentioned it a few more times. I loved the premise of punk rock fairies and wanted to check it out, but couldn't afford it.
Finally, when (August 23, 2003, in the blog) Neil's assistant Lorraine was cited as claiming that Millar's as-of-yet unpublished book "Lonely Werewolf Girl" might be the best book ever written, and then (Novemeber 2003, at Sequential Tart) Neil namechecked him again, I made it my mission in life (I'm a writer, bookseller and rare book scout) to track down a damaged copy. They wanted $54 for a scrunched copy of the Collected with a bite out of the back cover and the title page torn out. (I paid $38 plus $4 shipping, but -- at this point, rabid -- I really needed it.)
I've only read "The Good Fairies of New York" and have two entire Millar novels to go. It's ingenious. He ambles between traditional fairy motifs and the Gods of Punk Rawk. Deftly and cheerfully, he spins the stories of characters that mainstream bestsellers tend to skip. Millar's favorite writer, according to his website, is Jane Austen. It shows. Whimsically and precisely, with a fun plot that turns corners on a dime, all sorts of delicious mayhem ensue. If you've ever wanted Johnny Thunders of The New York Dolls to come back from heaven to find his lost guitar, or if you've ever wondered why reels can be so tricky on the fiddle, or if you've tired of some of the more traditional types of fantasies, the book's for you.
If you're as poor as I am, get Kelly Link's "Stranger Things Happen" or Matt Ruff's "Set This House in Order" or Jonathan Carroll's "White Apples." They're all in print in paperback. But if you've read those (and Gaiman and Kiernan and Mieville and the others pushing things forward), then treat yourself to "The Good Fairies of New York." It's wrong that it's out of print and so expensive, but it's oh so worth it.
