Thirteen-year-old Grace Thibodaux knew that she was a lucky girl, probably the luckiest girl ever. Both of her parents, Joe-Joe and Em, loved her so much. Grace loved them too. Their home was filled with music and laughter. Every day they taught Grace something new.

Having Down syndrome, some things came easy to Grace; others were more difficult for her to learn. However, she always thought of what Em said: "That does not define you, Gracie." In other words, Down syndrome was just one part of Grace, like her dimples or brown eyes. Em had a way of explaining such matters: "You can do almost anything if you want it enough, Gracie." Life was good.

Then on a December day, in the blink of an eye, the Thibodaux household changed forever. Gracie's beloved Joe-Joe was killed in a tragic accident. Her whole world was shattered on that day.

Grace didn't think it could get worse, but it did. She awoke one day, and she could not remember Joe-Joe's voice or his laughter. She thought that she was losing him forever. Grace knew that she had to do something to keep Joe-Joe in her mind and in her heart, and she had to do it alone. She couldn't tell Em; she was already so sad. After careful planning, Gracie embarks on a suspenseful journey that brings life lessons, friendship, and healing.
