Francine Prose‘s Reading Like a Writer: A Guide for People Who Love Books and For Those Who Want to Write Them is a fun, instructive guide for people who like to read word-by-word and study the craft. She includes tons and tons of excerpts from a range of genres. She also offers straight advice, and gently rebuts some "writing rules" like "show don’t tell".
Although I burned out by 150 pages (there’s only so much super close reading you can do in any given time), I still recommend this book to any writer or careful reader who wants to get better.
sounds good
