Reddit mentions of Book In a Month: The Fool-Proof System for Writing a Novel in 30 Days

Okay, so I'm not home so these are the few off the top of my head that I can remember I've read and loved.

• On Writing Well - this book was used for my Script Writing class in college - I loved it, and I still have it on my bookshelf.
  
  
• How to Write Science Fiction and Fantasy - This book by Orson Scott Card is genre themed, but I really suggest it no matter what genre you write. It's just a great source to have all around.
  
  
• No Plot? No Problem - Somewhat humorous take on those of us who procrastinate and have lots of writers block.
  
  
• Wonderbook: The Illustrated Guide to Creating Imaginative Fiction - Okay, so I haven't read this yet, but it looks amazing and I might actually just pick it up myself.
  
  
• Book In A Month - Okay, so this isn't really in the same category, but it's incredibly hands-on, fun book that can really, really, really help with outlining. I always suggest this book to people who participate in NaNoWriMo, because it's just super helpful.
  
  I hope one of these can help out!
