I plan to NaNoWriMo this year. Have started a few times before, but have a serious reason to finish (and publish) in 2018. (I need to prove that I can make an income from something other than "that Permaculture nonsense".)
What I would love to do, is to write or collaborate on a Permaculture guide for South Africans, as most existing information seems to be either American or Australian and the trees that they consider perfect for planting are either invasive species here, or simply don't do well in our dry, hot climate.
