It depends a bit on what you are starting with - state of your soil, variety and quantity/quality of muck you have available, kind of beds you are planning to use (or have already in your garden) etc etc.
I have used the "Organic Gardener's handbook" (M Littlewood) quite a bit and if you are in Scotland (or North of England) I can recommend K Cox and C Beaton's "Fruit & Vegetables for Scotland". Monty Don's Complete Gardener also has a good veg/fruit section, and there are quire a few books with "Organic" in the title in your library. Bob Flowerdew is quite good too. Best to get all the books from the library first and see which one you like most.
I have found the Charles Dowding books interesting if a bit irrelevant, as I am on heavy (with a capital H) clay soil that was arable until we took it over 7 years ago...
