"David Custance’s memoir not only tells the unbelievable journey of his sister’s resilience toward adversity, but it acts as a reminder of how precious life truly is. Told with warmth and humor, Sammy Knows It All lays bare the strength found in love, family and most of all hope. Wendy’s life is far from over, but what we can gleam from her now is the understanding that no matter how unfair the world may seem, we must keep on singing! This book is a marvelously powerful and inspirational read."
