Searching for topics for motivation for your writer’s group, I happened upon The Everything Guide to Writing Your First Novel by Hallie Ephron at my local library. I found it stuffed with tips and ideas from character development, to plot outline, to grammar, to publication.
The book offers a writer pretty much everything you need to know in a single spot, in simple language, and laid out in easy-to-find-the-information format.
Post your own “love-it-writing-books” in comments below, or post your own review and link. I’d be interested in the how-to books other authors feel worthy to mention.
