"It's April Fools' ay, and the Wakefield twins are about to play their biggest and best trick ever. Usually Elizabeth and Jessica pretend to be each other. But this year they won't switch identities--everybody will just think they did.
When April 1 comes, the twins' trick works perfectly--too perfectly for Elizabeth. Everyone believes she is Jessica pretending to be Elizabeth. And being Jessica always means getting into trouble. By the end of the day, Elizabeth is beginnng to wonder whether she is the biggest April Fool fo all for agreeing to be part of this charade."
