What can we all learn about tenacity and joy from children, even when they're unable to communicate verbally? Robert Rummel-Hudson, whose daughter was diagnosed at age 3 with polymicrogyria, a rare disorder that leaves her unable to speak, will join us this evening to discuss his family's triumphs in the face of an extraordinary challenge. His book is "Schuyler's Monster: A Father's Journey with His Wordless Daughter" (St. Martin's Press, 2008).
