Charles and Emma: The Darwins' Leap of Faith is a 2009 Young Adult nonfiction book describing the marriage of Charles Darwin and Emma Wedgwood, a devout Christian. Charles was both an agnostic and working on a theory that she regarded as wrong and blasphemous...this is the story of how they made it work anyway, and how Charles's love for Emma shaped his career. The book was published to coincide with Darwin's 200th birthday and received widespread critical praise.
