@thesamurai13579 you can add it to the second book by continue the story by where it ends for example my first book can end off one threat down but a new threat starts to appear, the start of the second one continues from the new threat that won't be there but the adventurer sees something off and that's due to the new threat. Or an another example tells a completely new adventure for the adventurer in the second book that tell a different story from the first. So If you know how you're story gonna end. Think about the second, do you want to have an new adventure and tell it as a new journey or do you want to have your story at a cliff hanger and start the second from there on. How do you feel you want your second book to add or not?
