Hey there,1~To write a novel, there must be research.Go to your local labirry or bookstore and take out/buy a few different thriller novels. Read them and look for inspiration from them. Know the style that thriller novels are written in.2~Plot out your novel. Start with the characters. You need a protagonist as well as an antagonist. Depending on what type of thriller novel you’re writing, some characters may have to have specific traits, such as being insane, or being a spy. Then move on to the plot of your book. If you find it hard to think of a good storyline to get your novel going, think of a particularily creepy or disturbing memory of yours and base your thriller on it. If it helps, make a plot diagram and write specific parts of the story at one time, such as the introduction, climax, or conclusion. You don’t have to start writing with the introduction. Do you have a really great conclusion in your head? Don’t let yourself forget it! Write it down and let your story develop from there!3~ Write your story! Sometimes the plot will just come into place and BAM! You have a thriller novel. Other times, you may get stuck or get a case of writer’s block. Take a break from your novel and come back to it when you have a fresh idea.4~you’re trying to get this novel published, you’ll most likely have a deadline for it to be into the publisher. Tell yourself to write one page a day, one chapter a day, or fifty pages a day (as an example) depending on your personal abilities as a writer. Push yourself, but don’t do anything impossible. Also, if you’re writing this novel for a school project, you’ll probably find it easier to make a timeline. If you’re writing this novel for fun, a timeline isn’t entirely necessary.Good luck~ＤＲＡＧＯＮ~
