The Letter from Hogwarts

The Letter from Hogwarts is the third chapter in the fanfic Harry Potter and The Philosopher's Stone.

Summary
After the long wait, Harry finally receives his letter from Hogwarts School of Witchcraft and Wizardry. The next week, for Harry's birthday, the family threw a party for him, inviting Remus and Sirius, along with wizarding families who were friends of the Potters and Minerva McGonagall. Near the end of the party, Harry overhears a conversation about him and his parents sit him down to talk with him, waiting for their last guest, Hagrid, to arrive.

Deviations from Canon

 * Harry knew to expect a letter from Hogwarts. In fact, he was beginning to get concerned with anticipation.
 * Like in canon, Harry received his letter a week before his birthday, but because he was not prevented from receiving this letter, no subsequent letters were sent.
 * Unlike the Dursleys, his parents never tried to prevent Harry from receiving his letter.
 * As such, only one acceptance letter was delivered to him
 * Harry received his letter from an owl, instead of Hagrid.
 * Harry's birthday is a big celebration for his family.
 * Many of the children Harry met at Hogwarts in canon are present at Harry's birthday party as family friends whom he has known for years, including the Weasley children, Susan Bones, Ernie MacMillan, and Neville Longbottom.
 * Neville Longbottom is raised by his parents, whereas in canon, Neville was only raised by his grandmother, with his parents unable to raise him, as they were tortured into insanity by Death Eaters.
 * Both Prewett brothers were killed by Death Eaters in 1981 in canon, but are present at Harry Potter's birthday.
