There are many How To Write books out there, including my favourites:
On Writing: A Memoir of the Craft by Stephen King
Story: Substance, Structure, Style and the Principles of Screenwriting (Methuen Film) by Robert McKee
From Pitch to Publication by Carole Blake
Becoming a Writer by Dorothea Brande
and my latest purchase, Why Will No-One Publish My Novel?: A Handbook for the Rejected Writer by Fay Weldon
All writers wishing to submit their novels to an agent should probably own the latest copy of The Writers’ and Artists’ Yearbook 2019 by Bloomsbury Publishing
