A great list compiled by the writers of the NHWN blog. Some books include Brenda Ueland’s Bird by Bird. Although not a technical book, a personal favourite is Writers Write by William Meikle for motivation and getting over emotional roadblocks along the way to developing your craft.
If you are looking to get into the mind’s of great writers–after all imitation is the sincerest form of flattery–then I would check out Reading Like a Writer: A Guide for People Who Love Books and for Those Who Want to Write Them by Francine Prose.
