This book is a must-have (I feel like I say this about all the writing craft book I review, lol)! KM Weiland helps guide you through creating your character's Lie and how you can shape their arc to embrace the Truth, tying their emotional arc in with the plot across the 3 Acts. She explains the course of a positive, flat, and negative arc, and even how to plot arcs across trilogies and series (much appreciated!).
