Okay so a couple of things before I start this book. I know it looked like Liz rediscovered Phineas was her step-brother and that was a big mistake on my part, but I'm working it to my advantage. Liz can't stand the fact that she and Phin are related so she's in denial and freaks out whenever someone mentions it. Next, in the epilogue when Phineas was writing to Ferb in the fake letter and he referenced AT2D, the reason he remembered was Carter's control over his mind shook those memories loose. Amnesia is a suppression type thing. Also, you can't trust me. Not with books. I'm very forgetful and some things aren't gonna make sense. Bear with me. If you ask, I will edit some things though. You can ask about any book I've written, even if they're done. I care about what you guys think, so I will do things to make it better for you. Last thing – I was going to make this book three years later, but I've decided on five instead. Which somehow puts Phineas at seventeen, Isabella at sixteen, Ferb at twenty, and everyone else in relation to those guys. Thanks for reading and reviewing (those of you who do) your feedback means the world to me. Enjoy!

Prologue

The girl was on the bus, staring out the window with her chin resting on her hand. Her eyes had a faraway look in them, like she was somewhere else entirely. Which was pretty close to the truth. After a messy breakup with her jerky boyfriend, she had moped around the house for a couple weeks until her parents had forced her out of town – out of the actual freaking country – to a summer camp in the Rocky Mountains.

She hadn't even wanted to go rock climbing anyway. What was there that tempted people so much? Yeah you got to the top and the view was great, but you could get that on a postcard at any dime store in any of the places the mountains touched. And when you got to the top, there was the view and oh yeah – more rocks. And then you had to climb all the way back down.

She sighed. It wasn't that she didn't like the idea of climbing a mountain. On any other day she probably would have jumped for joy at the opportunity. But now what she needed wasn't an adventurous climb to the highest point in North America, what she needed was to go home. And not Mexico home, with her parents and younger brother and so-called friends. Home home, with her real friends she had left behind without saying goodbye and the summers that lasted forever and the kick-butt girl scouts and the best day ever. She wanted Danville. She wanted Phineas Flynn and Ferb Fletcher and Addison Sweetwater and Perry and even Candace and that weird pharmacist that occasionally stalked them.

"Homesick again?" the raven-haired girl looked up at the sound of a familiar voice. The boy sitting next to her was taller than she was, with a hoodie and baggy jeans hiding his features. She smiled wanly.

"Normal clothes just don't work on you." She replied.

"Can't say I didn't try." He shrugged. "But you are homesick, aren't you Isabella?" Isabella Garcia-Shapiro sighed heavily.

"yeah, I really am. Where have you been? I haven't seen you in at least two years." She frowned, glaring angrily. "Do you know how hard it was for me not to have anyone that I could talk to besides Pinky, who isn't even there half the time?"

"I'm sorry, I'm sorry." The boy replied, holding up his hands. "I was really busy helping the resistance in Danville."

"The what?" Isabella asked, instantly concerned for her friends' safety. "Are you okay? Are the others okay? What's going on?"

"The World Division took over the US, Isa." The boy said solemnly. "But they did it so efficiently no one on the outside even knows. Phineas and his band of rebels have been fighting them for five years."

"What? I have to help them! Why didn't you tell me this before?"

"Phineas told me not to. And I didn't think you were ready. But now might be the only chance we have to save everyone. I have intel that suggests the WD is up to something a lot bigger than world domination."

"Bigger than world domination?" Isabella gasped.

"Yes. We need all the help we can get. Which means your help, Isabella. Do you trust me to keep you safe?" The boy leaned closer, holding out a hand. After a moment's hesitation, Isabella placed her hand in his.

"Of course I do, Beovulph." She replied.

The next second, both teens were gone. As if they had never been there at all.

So….yeaah. What did you think? I'm hoping that this one will make me proud. How do you think it's going so far?
