In this inspiring, life-affirming tale, Annabelle asks, "What happens when we die?" Aiden dreams of an afterlife with marshmallow shoes and chocolate kangaroos. But with the help of their dear friends like the Skeptisaurus and Tardigrade Tom, the children discover what we do know, and how worth celebrating it is. How our atoms rejoin the universe, which remains forever changed by our lives. How our energy lasts forever, along with the stories of our loved ones we keep alive by honoring their memories. And most of all, how mortality can inspire us to appreciate the incredible opportunity we've been given: to live the best, most meaningful lives we can, surrounded by the people we love.
