Helen adored her beautiful golden Labrador from the first moment he was placed in her arms, a squirming fat sausage of creamy yellow fur. As her best friend, Friar Tuck waited daily for Helen to come home from school and play. He guarded her through the long, scary hours of the dark night. Twice he even saved her life.

Now it's Helen's turn. No one can say exactly when Tuck began to go blind. Probably the light began to fail for him long before the alarming day when he raced after some cats and crashed through the screen door, apparently never seeing it. But from that day on, Tuck's trouble--and how to cope with it--becomes the focus of Helen's life. Together they fight the chain that holds him and threatens to break his spirit, until Helen comes up with a solution so new, so daring, there's no way it can fail.
