Book excerpt: Calvin Sharpe is a young black man growing up all too quickly in the 1970's Deep South. His story takes the reader through one traumatic experience after another on his way to the successful life he always dreamed of; but was that dream really a nightmare? The suspense-filled novel, "What You Don't Know Can Hurt You" ingeniously weaves together the events surrounding the lives of Calvin Sharpe, an out of place country boy who eventually becomes a successful Atlanta entrepreneur; Miss Letha, his self-consumed, self-righteous grandmother; Zelda, his seductive high school sweetheart; Lavender, the hilarious, street-smart character who dances in and out of the story; Paul, Calvin's captor and tormentor; Zavier, his male lover; and Siri, a character with a shocking secret of his own. The novel is filled with witty characters, steamy romance, realistic interactions, incredible irony, suspense, murder, and a surprise ending that will blow the reader's mind.
