I recently purchased Four Season Harvest, by Eliot Coleman. I haven't had a chance to start it yet, but it came highly recommended by a few friends that are avid gardeners and said it's the most used book they have and highly recommended it.
Veggiewhisperer - did you get that book? if so, what do you think of it? I think that sounds interesting and I just adore Michelle Obama - I think the awareness she has brought towards homegrown foods, nutrition in schools, etc. is admirable.
