Here are four books on writing I just finished reading that you may find of interest. These books give insight into the nuts and bolts of the writing life, fill in the backstory of how writers craft their ideas, show how to read critically, and discuss why books and writing are important.
How to be a writer in an internet world
This book, Booklife: Strategies and Survival Tips for the 21st Century Writer
, by Jeff Vandermeer, is probably the best, single-volume source for how to be a writer today. It contains strategies, tips, plans, advice, guidance, and motivation for almost all phases of life as a writer, from setting up a healthy and productive work schedule to networking to using social media platforms like Facebook to working with editors to dealing with fame and publicity.
Really, this is a useful book.
Reading like a writer
In Reading Like a Writer: A Guide for People Who Love Books and for Those Who Want to Write Them
, Francine Prose walks us through pieces of model stories written by great writers, helping us train our eye for good technique in the elements of writing good fiction, focusing on individual words, sentences, and paragraphs, as well as dialogue, character, and other components important in making a work enduring and memorable.
Listening in as an author writes a story
In Ron Carlson Writes a Story
, author Ron Carlson lets us listen in, piece by piece and draft by draft, to his thoughts and motivations as he writes a short story. Kind of like looking over the shoulder of a professional writer at work.
Reflections on the life of a writer
In A Dangerous Profession: A Book About the Writing Life 
author Frederick Busch presents a collection of essays musing on authors and works he likes as well as insights into the life of a writer based on his own experiences as novelist, critic, and teacher.
