The book you need more than any other for Northwest gardening is the Seattle Tilth's Maritime Northwest Garden Guide. It's a paperback, about $15.00, and should be available from nurseries or bookstores in your area. If not, you can get it from them directly at www.seattletilth.org.
I know some serious home gardeners in the Bellingham area. I'll have to invite them to the play on the site.
