Amazon.com Review What to make of a book called A Heartbreaking Work of Staggering Genius: Based on a True Story ? For starters, there's a good bit of staggering genius before you even get to the true story, including a preface, a list of ''Rules and Suggestions for Enjoyment of This Book,'' and a 20-page acknowledgements section complete with special mail-in offer, flow chart of the book's themes, and a lovely pen-and-ink drawing of a stapler (helpfully labeled ''Here is a drawing of a stapler:''). But on to the true story. At the age of 22, Eggers became both an orphan and a ''single mother'' when his parents died within five months of one another of unrelated cancers. In the ensuing sibling division of labor, Dave is appointed unofficial guardian of his 8-year-old brother, Christopher. The two live together in semi-squalor, decaying food and sports equipment scattered about, while Eggers worries obsessively about child-welfare authorities, molesting babysitters, and his own health. His child-rearing strategy swings between making his brother's upbringing manically fun and performing bizarre developmental experiments on him. . After presenting a self-effacing set of ''Rules and Suggestions for the Enjoyment of this Book'' (''Actually, you might want to skip much of the middle, namely pages 209-301'') and an extended, hilarious set of acknowledgments (which include an itemized account of his gross and net book advance), Eggers describes his parents' horrific deaths from cancer within a few weeks of each other during his senior year of college, and his decision to move with his eight year-old brother, Toph, from the suburbs of Chicago to Berkeley, near where his sister, Beth, lives. In California, he manages to care for Toph, work at various jobs, found Might, and even take a star turn on MTV's The Real World. While his is an amazing story, Eggers, now 29, mainly focuses on the ethics of the memoir and of his behavior--his desire to be loved because he is an orphan and admired for caring for his brother versus his fear that he is attempting to profit from his terrible experiences and that he is only sharing his pain in an attempt to dilute it.
