A/N: This is not a Pureblood!Hermione story. This is just my idea of Hermione as a Slytherin, being eventually pursued by the Weasley Twins. It's a slow burn of a romance, but there is actually other stuff happening as well, so I hope you enjoy it.

Keep in mind that the twins were born 1 April 1978 and Hermione was born 19 September 1979, making them almost 1 1/2 years apart in age. So, regardless of what they get up to here, the age difference is negligible and remains constant.

For dates and other references, I have relied on the Harry Potter Lexicon and Harry Potter Wikia. If a real-life calendar contradicts the calendars on those sites, I adhere to the calendars from Time and Date dot com.

I am following along one of the fandom trends and naming Hermione's parents Daniel and Emma. The Wikia doesn't give the Doctors Granger first names, so those are the ones I chose. I eschew canon at will. AU, for the win!

This story is complete on my end and will be posting Tuesdays and Fridays until it's out in its entirety. I love to hear from my readers and do my best to respond to each reviewer if they're logged in and accepting PMs.

Now, I'll try very hard not to have such a long author's note again. :)

Prologue

Hogwarts, 7 July 1990

The Headmaster stroked his beard as he eyed the Letter List for the 1990-1991 school year. Over his shoulder, Fawkes—his phoenix familiar—issued a querulous note of song that made one of the names on the parchment vibrate with a sort of odd shimmer.

"What is it, lad? I don't know why she's on there. Her birthday isn't until the nineteenth of September." Dumbledore was set to cross her name off the list but Fawkes shrieked and made a quick hop from his perch to the broad, crowded desk where his wizard presided. "Fawkes. You know the rules. Yes, she is a year ahead in her primary school, but that doesn't mean she'd do well, here. She's Muggle-born."

The Letter List was a magical construct. On this day every year, names would appear on it, as well as dates of birth, along with prospective students' proper addresses. He and Minerva would set the quills to writing the usual Welcome to Hogwarts letters and then they'd add other notes as needed. The parchment would empty itself within seven days and remain empty until the next List was created.

Every year, Albus studied the List thoroughly. He wanted to know what names to expect, what families would be represented, and what their presences might do to the careful balance of politics and education that prevailed over Hogwarts.

From the wall, Phineas Nigellus Black snorted in his portrait frame. The former headmaster set aside the tome he had been reading and made a disparaging sort of sound. "Listening to creatures are you, Albus? Really."

"He's a phoenix, Phineas. Of course I listen."

"Well," Headmaster Black said after a moment spent drumming painted fingers on a painted book, "Really, if she had been born three weeks earlier, she'd be starting this year, no? Children do arrive early on occasion."

Against his will, Dumbledore chuckled. "You're right, Phineas. They do. And I suppose that a difference of less than even a full moon's cycle isn't significant to argue with the Letter List. Fine, I'll invite her."

"You might even consider making that an option for the Letter List," the former headmaster opined from his place on the wall. "If the Muggle-born does well, that is."

Albus cocked his head but made no comment. He had never let an underaged witch in to Hogwarts since he'd become headmaster. "I suppose," he said after a few moments, "I have the standing to try something new."

"You could always blame Fawkes," Black said with a smirk.

The phoenix flared his wings, unamused.
