Prologue
I looked up. Phineas jumped on Ryan, yelling. "Phineas," I barely got out, "no. I'm... I'm not worth it." He didn't seem to hear me. Ryan lunged on him. "No, Ryan. It--it's me you want." Ryan turned to me. He smiled that evil smile.

"Bobbi!" Phineas yelled as I passed out. I knew it was too late. I didn't struggle. It would be no use.

"Better me than you..."

Chapter 1
Three in the morning. A frantic, quick knocking, then the doorbell.

A twelve-year-old boy with a triangular head and messy scarlet hair groggily rolled out of bed. Phineas Flynn woke up his step-brother, also an twelve-year-old with messy green hair and a plump, stick-out nose.

"We should get that," Phineas told Ferb Fletcher. "You know how Candace is this time of day." They boys' parents, Linda Flynn and Lawrence Fletcher, were at an antiques convention until the end of the month. Candace Flynn, their obsessive, fiesty teenage sister, was in charge until then. She usually abused her power as "Supreme Overlord of the House", but ever since her relationship with her boyfriend Jeremy has gotten serious, she had been to busy to worry about her brothers.

Phineas and Ferb opened the door as soon as whoever was there started knocking again. It was a girl, about sixteen. The first thing Phineas noticed about her was her hair: it was pink, like bubble gum, tied in a ponytail with several strands falling on her face. Her eyes were fearful, pleading, golden with flecks of red. She was wearing a purple T-shirt and jeans with fresh rips exposing her waist and parts of her legs. Three rips on her legs looked as though they were caused by an animal attack. There were several scratches on her arms and neck, mud caked her shoes. She was sweating.

"Uh, are you okay?" Phineas asked.

"What do you mean?" the girl asked. Her voice was like a little girl's but also kind of rough, like she'd gone days without water.

"What do you mean what do I mean? You're all banged up, dirty, sweaty. You look like you've been attacked by a wild animal!"

"I wish."

"Do you want to come in? We can get you cleaned up, maybe call for help."

"Oh, thank you!" She walked in and shut the door behind her. "Are you guys Phineas and Ferb?"

"Yeah. Why?"

"I came to your guys' house on purpose because I knew you guys would believe my story, based on all the incredible things you guys have done. Although it's late. You guys should get to bed."

"Hi." Phineas and Ferb turned around. A twelve-year-old girl with curly, messy green hair reaching to the floor and a nose much like Ferb's only smaller, had appeared. "My name's Jessie. I'm Ferb's sister."

"Hi Jessie. I'm Bobbi. So Phin, can I stay here just for a few days? I'm in trouble. And trust me, we're all safe as long as we don't leave the house. Well, we can as long as I'm with you. I--just trust me."

"Why should we?" Phineas asked. "We don't know anything about you. Are you not going to tell us the story because you need some time to think up something believable?"

"No! You guys just look tired and I don't want to keep you up."

"I don't think I can trust you."

"We can," Ferb said. "She's... trustworthy."

"Yeah," Jessie agreed. "She can stay in my room."

"Thank you, Jessie." Bobbi and Jessie walked upstairs. Ferb followed but Phineas grabbed his arm.

"Ferb." Phineas looked at his brother. "She's so... mysterious and evasive. She seems to be avoiding the point. I'm picking up a vibe of evil from her."

"I know you don't trust her," Ferb replied, "but she was obviously in danger. She's not evil, she was being chased by evil."

"Or it's the other way around."

"That's a chance I'm willing to take. And I hope you are too, bro."
