Pick a book that is handy. Fill in the numbers of the first and last pages. You can also use Kindle location numbers or any other numbered list. Click on Enter. Look at the numbered indicated to spark your creativity. Reference books (i.e. dictionaries, almanacs, etc.) are best. Novels and other large works of fiction (i.e. complete works of Sherlock Holmes, etc.) are also great. Books of poetry provide wonderful results as well.
