I’m kinda in love with The Writer’s Coloring Book by Rachel Funk Heller. I’m not much of a fiction writer, but how can I resist “paper dolls for grown-ups” as a way to envision your character and “Building a Story World Mandala” to build an infographic of the character in his/her world before the first plot point?
The book brings the perspective of the right brain together with that of the left brain. The passionate dreamer collaborates with the rational organizer to develop plots into layers that make them worthy of being called real stories.
I haven’t used one yet, but it’s definitely going on my wishlist. It looks amazing!
