So, a friend of mine (mamishka) wrote and published an episode guide to Joss Whedon's Firefly series. You can order copies from her directly, or from the publisher, via her website ( http://mediababe.org ). The main page has a link, or you can follow the 'What's New?' link, to order.
She's a slightly better deal than the publisher. They're selling them for $10.39 + $5 for shipping. She will be selling them for $15 each, shipping included inside the US. International will cost a bit more.
Any books bought directly from her will also be signed.
