A to Z open source ecomm book for beginners?

The topic says it all, I have been working the search engines overtime to try and find relevant, non-ancient material on this stuff, but alas I can find naught. There are pleanty of piece-meal articles around on the net but I can't find a comprehensive, technical book for beginners on the subject. I had seen one advertised on either webmonkey or here on devshed but I didn't act right away and now I can't find the link. The book wasn't actually complete but was taking pre-orders. Any help in this regard would be great. Thanks
