Highly recommended if you're a writer or an avid reader. This is a combination memoir (as the title says) and King's philosphy on writing. You won't find many How-To lists here, but his advice is invaluable and mirrors what other writers have said on the craft of good writing.
I love his concept of unearthing a story in the way an archaeologist uncovers a fossil. The idea of being completely truthful in work rang true, as well as many of his pointers on character description.
My only experience reading King's work prior to this was 400 pages of the epic 1,000+ page "It." I had no allegience to his work. I've seen some of his movies, but I'm definitely interested in reading his work.
