BEING HENRY DAVID by Cal Armistead
Seventeen-year-old "Hank" has found himself at Penn Station in New York City with no memory of anything --who he is, where he came from, why he's running away. His only possession is a worn copy of Walden, by Henry David Thoreau. And so he becomes Henry David-or "Hank" and takes first to the streets, and then to the only destination he can think of--Walden Pond in Concord, Massachusetts. Cal Armistead's remarkable debut novel is about a teen in search of himself. Hank begins to piece together recollections from his past. The only way Hank can discover his present is to face up to the realities of his grievous memories. He must come to terms with the tragedy of his past, to stop running, and to find his way home.
