Here is another good book to help children deal with death and the grieving process:
The Sound of the Sea
Jacqueline Harvey & Warren Crossett
Sam Sullivan remembers the precious times he spent with his mother before she became ill and went away. With the love and support of his grandparents, he gradually overcomes his anger, bewilderment and grief and begins to understand that, although his mother is gone, she will always be with him.
