Blubber

Blubber is a good name for her, the note from Wendy says about Linda. Jill crumples it up and leaves it on the corner of her desk. She doesn't want to think about Linda or her dumb report on the whale just now. Jill wants to think about Halloween.
But Robby grabs the note, and before Linda stops talking it has gone halfway around the room.
That's where it all starts. There's something about Linda that makes a lot of kids in her fifth-grade class want to see how far they can go -- but nobody, least of all Jill, expects the fun to end where it does.
