K.M. Weiland has some really fantastic books. I have especially loved her books on writing. Among my favorites so far are her ‘Outlining Your Novel’ and ‘Structuring Your Novel’. Structuring especially has been very helpful. So check out her website to see for yourself!
Here’s a great look at her ‘Outlining Your Novel’
As an affiliate, I don’t get any monetary compensation for advertising this particular author, though I am a member of her Wordplayers group and get free books to review. Again though, as always, I don’t endorse or advertise something that I don’t believe in! And her writing how-to’s have already proven very helpful.
