Summary
Believing that everything in his life could be fixed if he had only become class president in High School, Heinz Doofenshmirtz uses his past invention, the De-Age-inator, to become 18 years old again and quickly enrolls in Danville High. However, in the high school political arena, Doof faces fierce competition from his opponent, a girl named Candace Flynn, whom smells something fishy about the new "exchange student" and soon sets out to bust him!
When the two are paired as soccer rivals and then lab partners, though, their mutual understanding soon works against them and turns their fierce rivalry into something neither of them expected.
Heinz now has to ask himself if he's evil enough to take his daughter's friend to the prom before taking over the Tri-State area, while Candace has to answer, once she gets the evidence she craved, if she's prepared to bust someone she's fallen in love with? And if she'll really be okay this time when everything disappears.
It seems neither teenagehood nor middle agedness is all it's cracked up to be.

After a large number of improbable events, a time paradox ends up merging two different places together. Doofenshmirtz teams up with Hawkmoth whether Gabriel wants him to or not. A lot had changed in Paris in such little time: butterflies terrorize innocent civilians, superheroes roam the streets, and the language barrier has magically disappeared—how convenient! With Doof on the loose causing mayhem in Paris, O.W.C.A sends Perry out to stop him, but as he’s only got partial jurisdiction there, he is forced to enlist the help of two underaged superheroes to help him fight his nemesis. Though not perfectly ideal, things were going pretty well, but there is one thing that nobody accounted for.

Summary
Middle school, how infuriating it could be. Phineas Flynn had been teased about his braces often, and stressed too. Seventh grade was a DISASTER. If only things could have been better. The constant nagging, the crushing on Isabella, the breakdowns. It was all too much. Candace ALSO had problems on her hand. She was working with OWCA, as she found out Stacy and Vanessa knew and that perry was a secret agent. Oh tell me, is this a good thing?
