While I already knew much of what was explained in this book, the way it was laid out and the quick exercises to complete gave me a new, deeper understanding of deep PoV. This book contains tidbits that took all the puzzle pieces I already knew and worked with, and slotted them together in a way that has changed my viewpoint while strengthening my prose. Plus, being free on KU, if you happen to know everything already you aren't out anything.

This is a quick, powerful read, and I recommend it for all writers.
