On a late, winter afternoon in the Fifties, the travelling dentist and his assistant daughter, Dolly, take a dangerous boat trip across Ripple Rock to a sore tooth at Mrs. Davis' house on Quadra Island. While her father tends to Mrs. Davis, Dolly meets Chuck, on the pretence of studying, but is distracted by falling in love. Years later, in the face of a woman she's never met, she discovers the details that tell a different story -- and finally sees what she missed that stormy night.
