Why did Frank McCourt's Angela's Ashes , a memoir of his poverty-stricken childhood, touch millions? Why did John Steinbeck's The Grapes of Wrath and Upton Sinclair's The Jungle incite social change and become literary classics? Why did Sebastian Yunger's real-life adventure A Perfect Storm leap onto the bestseller list? In this book, Philip Gerard analyzes books that made a difference-fiction and nonfiction, classic and contemporary-distilling out the elusive ingredients that make a work memorable, one that changes our minds and our lives. Beginning with the importance of choosing powerful subjects and themes, Gerard encourages writers to explore what is closest to their hearts. He then presents dozens of practical storytelling strategies that engage readers and move them- to tears and laughter, or to action. As in his much-praised Creative Nonfiction , Gerard's instruction is always accessible and a pleasure to read. Anyone who dreams of writing a book that makes a difference will come away with a clear understanding of what it takes to succeed.
