So like a summary about it? Easy. Just write the things that happen (without spoilers!) and its really simple ... Here's an example, but its prefered for you to make your own ... : A Wrinkle in Time is the story of Meg Murry, a high-school-aged girl who is transported on an adventure through time and space with her younger brother Charles Wallace and her friend Calvin O'Keefe to rescue her father, a gifted scientist, from the evil forces that hold him prisoner on another planet.
