As I said in a previous post, I use to think that craft books were for the egotistical author who thinks they know everything, however, I released I was the prideful one. I now look for craft books for genre specific, as well as overall construction of your manuscript. Here are three I found most insightful:
The Art of Fiction by Ayn Rand: it’s a general book about writing fiction. It is actually a compilation of notes from a series of lectures Ayn Rand gave for her students and colleagues.
