The Invisible Enemy

Alyssa is mean, sarcastic, and just plain no fun. Billie Stoner considers her to be an enemy and sometimes wishes that Alyssa would just disappear. That’s exactly what happens when Alyssa snoops in Billie’s knapsack and accidentally makes herself invisible with Billie’s secret powder. Now it’s up to Billie to help somebody who has made her school life a total misery. Will she be able to save Alyssa? Does she even want to?

Young readers, who were delighted by Billie Stoner’s adventures in The Invisible Day and The Invisible Harry, will be thrilled to see nasty Alyssa get her comeuppance – and Billie make an improbable new friend.
