Help! I'm Trapped in My Sister's Body — Todd Strasser

Jake's not the guy he used to be.

Jake Sherman is in a real jam this time. His online pen pal, Sumi, is coming for a visit and Jake has kind of led her to believe that he's a star athlete... a slight (make that total) exaggeration of the truth. So now Sumi is expecting to see Jake Sherman, football hero. Not Jake Sherman, regular guy. The situation seems hopeless until Jake gets the brilliant idea to switch bodies with someone who is great at sports.... Unfortunately the only star athlete he knows is his sister, Jessica!

But can a guy who bites his nails ever get used to polishing them?
