All Sarah and Evan Davis ever wanted was a child, but after two dangerous miscarriages, they face an unbearable-and uncertain-future. Evan tries to console her, but Sarah refuses to be swayed. Against doctor's advice, Sarah allows herself to get pregnant, and this time gives birth to a beautiful boy, Kade. At long last, both Sarah and Evan believe their lives are complete, at least until their son is diagnosed with autism, something neither of them expected-a change that leads to an even harsher reality: sometimes love, no matter how hard, must be enough.
