Exactly what the title suggests: 642 interesting, varied and sometimes difficult subjects, starting points or questions - all of which will solve the problem of what to put on the page, and will flex your writing muscles. From the introduction: "You could use these 642 things literally, by picking an exercise and completing it. Or you can just let them wash over you to stir up your creativity, to remind you that no, not everything has been written, not every good idea has been taken by someone else. There are an infinite number of things one could write about and so many fresh directions for your story to go." This book was created in one day by the members and friends of the San Francisco Writers' Grotto.
