So, I always thought the synopsis was what you would see on the back of a book, briefly discussing the central settings, characters, and themes, hinting towards the conclusion of where the story would lead. Apparently I am wrong? Most agents require a synopsis upon submission, so this is always what I used... Not quite sure what the difference is between a synopsis, abstract, summary and overview are now. All the definitions are jumbled as heck. Anyone brave enough to specify?
