To write a short summary for a book such as "Bud, Not Buddy," start by re-reading important parts and taking notes. Next, outline the plot and themes, and begin writing an opening paragraph. The last steps are to use the notes to summarize the plot and ending.
When taking notes, include only the main characters and themes. Also, take notes about any part of the book that stands out. Divide the notes into sections according to the plot development. Write a short outline of the plot and themes using the notes, and keep it simple; minor details are unnecessary.
The opening paragraph of the book summary needs to include the book title, author and a description of the book's premise in three sentences or fewer. Use each section of the notes to write a summary of the story development. Write an even amount for each section, not lingering too long on a single part. To keep it short, avoid writing about minor characters, side plots and opinions.
To summarize the ending, write about the climax of the story, but do not directly give away the ending if the summary is intended for a wide audience. For an optional ending to a book summary, discuss the main theme of the book.
