There are a LOT of good books out there that can help, but I personally have 1 book that I recently read and has helped me a ton in planning my stories, figuring stuff out, breaking scenes down and making sure everything works.
The book is "The Story Grid: What Good Editors Know". Now the funny this is that the entire thing is also available online for free. You can find everything about the book and additional resources here --> https://storygrid.com/
I recommend you buy the book (if you can afford it) and you will not regret it. I have filled mine with post-it notes and I keep referring back to it as I plan my stories. It's amazingly useful, and the main use of it is after you have finished putting down at least a first draft of your story. This has changed the way I approach my stories and I recommend it to anyone who has trouble keeping track of their stories and wants something to help them keep everything in order.
