I have been trying to find the title and author of a book I read some time ago. I read it in an edition of Reader's Digest Condensed Books. But unfortunately I do not remember which selection. Anyway it was a story of a school bus accident during a winter storm.
Can you help me?

You might try contacting someone on the following site: Reader's Digest (http://www.rd.com/)

"The Sweet Hereafter", by Russell Banks is a book about a school bus crash in the Winter. Is this what you are thinking of?

A synopsis:

"From Library Journal
One snowy morning in the small town of Sam Dent in upstate New York, a school bus careens into a frozen stream, killing 14 children. The Sweet Hereafter examines the aftereffects of this accident through the eyes of four narrators: the driver of the bus, a parent devastated by the loss of two children, an opportunistic big-city lawyer, and a permanently crippled teenager who survived the crash. Grief and an obsessive need to assign blame draw the townspeople together; all too quickly the focus shifts from what they have lost to how much they stand to collect in insurance settlements. Banks, who along with Raymond Carver, Ernest Herbert, and a handful of other writers has revived the genre of working-class fiction in the last decade, is uncharacteristically heavy-handed in extracting a moral from these proceedings. Not up to the high standard set by Continental Drift ( LJ 4/15/85). Previewed in Prepub Alert, LJ 5/15/91."

I believe the response above from shygrneyzs is the book you are thinking of-- they made a film out of it. Quite haunting.
