I decided to grab this ebook while it was free thinking it might be helpful in my 'structure' research, and I'm glad I did, because it was definitely worth checking out.
I enjoyed its simplicity, and the story examples Mercer used throughout solidified concepts she brought up (so if I had a misunderstanding about something, it didn't last long).
One thing I struggled with as I read was skepticism. All books have structure. Ok, agreed. But when she broke down the structure into percentages and stated that these events could be found in this range (10-12.5%, 22.5-25%, etc.), I admit I thought to myself 'there's no way this actually works...especially not for every novel'.
So I decided to try it out. Sadly, I chose Leviathan, which made the process messy because the author never goes into detail about how to analyze books with multiple protagonists and/or multiple points of view. Needless to say, that didn't work out great. But I found that it worked fairly well with other texts. And besides, the information I garnered about structure overall was worth the adventure.
For the price, it's a good deal. It's easy to follow, useful for writing your own novel (trying to match percentages to gauge structural integrity), and honestly...it's kind of fun to check out novels' percentages and see what works (and what doesn't).
