Jessica Brody approached the topic with a good mix of humor, clear instruction, and plenty of examples to back it up. I read this to help a friend with their YA novel, but the content is applicable across the board.

I compared a bit with the original Save the Cat! Writes a Novel, and the YA edition does seem to have some new content, or expanded content, especially in regards to plotting a series. Some chapters are also formatted in an easier-to-consume way. An upgrade overall, I think. 

Worth the read if you’re an author - YA or otherwise!
