Query: Every writer should get it

Helps you plot out your pacing so that your book never drags! Provides a template telling you exactly what needs to be happening at what point in your book by what page. (Obviously YOU created the outline for the action.) You can even place the template over and existing manuscript to show you what needs to be cut, added to or reshaped to make it tauter. Highly recommend to any author.
