Phineas was sitting under the tree and Ferb was sitting next to him. That's when they got their letters. Phineas might have suspected it if he knew it existed, but it changed his world when the owl dropped cream colored envelopes in his and his brother's laps. The heavy paper smelled like every story that opened up worlds to his vibrant imagination. Little did he know that in the green ink on the front of that envelope was a whole story waiting to unfold. Phineas opened his letter and carefully read the green writing.

HOGWARTS SCHOOL of WITCHCRAFT and WIZARDRY

Headmaster: Albus Dumbledore

(Order of Merlin, First Class, Grand Sorc., Chf. Warlock,

Supreme Mugwump, International Confed. of Wizards)

Dear Mr. Phineas Flynn-Fletcher,

We are pleased to inform you that you have been accepted at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment.

Term begins on 1 September. We await your owl by no later than 31 July.

Yours sincerely,

Minerva McGonagall

Deputy Headmistress

He glanced at Ferb's paper, that contained the same message. It only took a minute to realize what this was saying. They were wizards.

"Well Ferb, I know what we're going to do today"

Ferb glanced at him and blinked in his usual unexpressive way. Phineas quickly took it as an affirmative response. It was then that Isabella, Buford, and Baljeet ran into the small, familiar backyard. They all held similar cream colored letters in their hands.

Skipping her normal greeting, Isabella asked, "Phineas, did you get a letter?" Her eyes were wide with unexpressed surprise.

"Yes, yes we did," Phineas said.

"What are they?" Buford asked impatiently

Isabella sighed, "They are our Hogwarts letter. You see, I come from a long line of wizards and witches. I knew I would get mine, but I could only hope you got your's since you're muggleborns. I thought Phineas and Ferb might be, because how else do you explain how they build those amazing things every day, and that they magically disappear every day? You had to be pretty strong wizards to have that kind of uncontrolled magic. Although Buford, I never would have guessed you and Baljeet were also wizards."

Baljeet spoke up "Actually, I am a half blood, my father was a wizard, but my mother is muggle born."

"This is great! We can all go together. What kind of classes do they have there, Isabella? What is it like? When do we start?" Phineas could hardly contain his excitement.

"I just hope we get in the same house!" Isabella replied

"What do you mean, Isabella?"

"Hogwarts is divided into four houses, and a sorting hat assigns you your house. Slytherin for ambition, Hufflepuff for the kind, Gryffindor fro the Loyal, and Ravenclaw for the clever."

"This is going to be great!" Buford responded

Phineas looked down at the list of things he needed and grew more and more excited for school to start.
