Books to explain death to chidren who lost their father

Hi ,
I am posting this for a friend of mine who lost her husband a month or so ago. THe children are aged 12, 10, 9 and 6. She said they have many questions about death and she is looking for stories
books with good answers to questiosn chidlren may have about God and death etc. Any suggetsions would be greatly appreciated. She is looking particularly for books/ stories that help them in a catholic context.

Blessings

Hello! I had just read your post and then saw this book while looking for something else. I haven't seen it, but but looks like it might be good. It's called After the Funeral. Here's a link: www.paulistpress.com/bookView.cgi?isbn=0-8091-6625-9. Mary
