Carry me down

"John Egan lives with his mother, father, and grandmother in a fragile household. The Guinness Book of World Records is his favorite book and he wants, someday, to visit Niagara Falls with his mother. But John has an unusual talent: he knows when people are lying and he is determined to become a world-famous lie detector - at almost any cost." "This novel, by the author of How the Light Gets In, is about John Egan's obsessive and dangerous desire to see the truth. Even as the action builds toward an unthinkable disaster, every word of Carry Me Down rings true."--BOOK JACKET.
