'Act Your Age' told through Phineas' point of view, with an extra little ending;3 Phineas and Ferb and all the characters belong to Disney! (Rated K+, might have some language)

After getting his Master's Degree after only two years of college, Phineas Flynn left early, married Isabella, and started his very own business.

Isabella Garcia-Shapiro. That's right. She's the girl who used to love Phineas. You're probably thinking, "Used to?!" Everything changed the day a certain green haired boy helped her after being rejected by Phineas. So why does she give up now? After all of the times,trying over and over,why does she quit loving Phineas. Ferb Fletcher. The guy who,if he would just open up,have probably a million girls going after him. So,why doesn't he open up to others? Why doesn't he want to talk to other girls? The answer is a simple 5 words. He loves Isabella Garcia-Shapiro. She loves Ferb Fletcher. To think,it all started with 2 little words. His Brother.

After a brief mention of their biological father, Phineas and Candace grow curious and decide to do some research, while Ferb wants nothing to do with it for unknown reasons. Little do the Flynn-Fletcher siblings know what they're getting themselves into. (Rated T for language and angst. TW later on)

When Candace and Stacy go through a falling out, the two are both in a world of hurt. Phineas feels guilty so he tries fixing their friendship. Meanwhile, in the future, the timeline has been altered so that the Flynn-Fletcher family has been breaking apart unexpectedly with these changes from the past. When two characters from the future try to fix the past, they have to hide their identity, but will it last for the rest of the story? Find out in "Mysterious Forces", a book based on Phineas and Ferb! Disclaimer: I do not own Phineas and Ferb or anyone except for my OC, Emma Hunter, and the plot. Rated Mature for some mature scenes, but nothing overly mature.

The Fireside Girls are prepared for any situation, or so they think. When a new member of Troop 46321 moves to Danville, they pick up on a few signals of affection towards a certain green-haired boy, and they work on their most difficult to earn patch because of the fragility of love, the Matchmaker Patch. But, what happens when a green ray shoots from the sky and mixes up things for Phineas, Ferb, Isabella, and Emma? Will they find love in the new relationship, or will everything break apart? Find out more in 'The Matchmaker Patch'!

When the gang enters their junior year of high school, Ferb is set on finding a girlfriend. He has been teased all through HS because he had a huge crush on a much older girl, Vanessa, who was dating someone else, and he wanted to prove that he could find someone. Little does he know, the girl he meets will change his life forever. There are a few mature topics/situations in here, but nothing explicit.

Ever wondered what it was like to be in someone else's shoes? Especially someone who was from your favorite show?
