Snowbound — Ann M. Martin

Let it snow, let it snow, let it snow!
The weather forecasters keep promising snow, but what a joke that is. Not a single flake has fallen on Stoneybrook this winter. How can SMS hold a Winter Wonderland Dance when it's warm enough to go to the beach?

Finally it does snow -- like crazy -- and no one's prepared. Jessi gets stranded overnight at her dance school. Mallory and Mary Anne are snowed in with the Pike kids. But Stacey's in real trouble. She and her mom were driving back from the mall when the blizzard hit. And none of the Baby-sitters have heard from her yet.

First they couldn't wait for it to snow. Now they can't wait for it to stop. Where could Stacey be?
