Definition: a condensed statement or outline (as of a narrative or treatise). A synopsis is a summary of a book that familiarizes the reader with the plot and how it unfolds.
Writing a synopsis that’s clear, concise, captivating… It is an overview of what happens in each chapter. A synopsis needs to tell the entire novel into one page. Yes, one. Try doing two; one that is 100 words and one that is 250 words… different agents want one or the other.
Tell about the main character, & the key points of their journey, primary conflict /obstacle… Character, goal, obstacle, resolution. NO hook, tell it flat out as it is. Don’t make the agent guess.
