The Wonderful Baron Doppelganger Device

W.B. is up against the cleverest, deadliest, most dangerous villain he's ever faced--himself.
Before we get to that, there's some good news: the new boy at school is the best friend W.B. has ever had! Of course, he is only the third friend W.B.'s ever had though, so... Anyway, his name is B.W. and he goes to the annual Pitchfork Fair with the Barons. W.B. loses his second ever friend, Rose Blackwood (who also works as his parents' assistant), after an exploding pie lands Rose in jail.
Then W.B. is abducted during a walk in the desert. How was he ambushed where there's nowhere to sneak up on someone? Because whenever W.B. decides to exercise, it's bound to end in disaster or pink and purple squirrels. Maybe both. With a bit of backside surfing, he returns to the Baron Estate to find he's been replaced--by another W.B.! It's no surprise that one of his parents' brilliant inventions is to blame for his troubles (although we shouldn't discount the lingering effects of exercising). The delinquent doodad is the Doppelgänger Device, which transforms the user into anyone with the simple press of a button.
Eager to get his comfortable life back, W.B. tries to expose the imposter. With his skin literally on the line, W.B. must prove himself by W.B.ing harder than he's ever W.B.ed before.

Eric Bower is the author of The Bizarre Baron Inventions series. He was born in Denville, New Jersey, an event of which he has little recollection, yet the people who were there have repeatedly assured him that it happened. He currently lives in Pasadena, California. His favorite type of pasta is cavatappi, his favorite movie is The Palm Beach Story, and he is the proud recipient of a "Beanology Degree" from Jelly Belly University in Fairfield, California. His wife and family have told him that the degree is nothing to be proud of, since "It's not a real degree. You know that . . . Right?" and "Eric, they literally give them to everyone who visits the Jelly Belly factory," but he knows that they're all just jealous.
