Let's start, to make a book the first thing you'll need is the title. But, think of something very important in your story that will fit into the title! You also need to answer these:
Characters:_____________________________________
Type of story:____________________________________
Problem:_______________________________________
Solution:_______________________________________
Let me give you an example;
Characters: Jess(Main) Sam(Jess friend) Jack(Jess brother) Heather(Jess adopted mom) Alex(Jess adopted dad) Iris(Jess 2 friend)
Type of story: Adventure
Problem: The flood
Solution: There really isn't one
Title: Wave's from the north
Please don't use this idea. I might use it.
After all of that, you need to think of the story description and all of the characters description. Isn't that easy?! :)
(Remember to use your own ideas)
