Does anyone know how to write a book?

6. I would recommend several books on writing by Natalie Goldberg, specificly one on writing memoir.

See https://nataliegoldberg.com/books/
Scroll down to "Natalie’s Writing Books"

The True Secret of Writing--Connecting Life with Language

Writing Down the Bones--Freeing the Writer Within

Wild Mind--Living the Writer’s Life

Thunder & Lightning--Cracking Open the Writer’s Craft

Old Friend from Far Away--The Practice of Writing Memoir

If you already know a lot about writing but don't know about to to make a book out of it, I'd suggest the last two. The first through fourth are excellent at teaching you how to write.

Good luck!
