Here are some of my favourites, only some, because I really, *really* want to rec everything that has been posted.
Title: Sing Me A Song by mihnn
Pairing: Harry Potter, Vernon Dursley, Petunia Dursley
Word Count: 1,688
Summary: For it is widely believed that one’s demons can easily be a figment of one’s imagination, but that doesn’t mean that it doesn’t exist.
Warning(s): Character death and torture
Notes: This story is amazing, what makes it even more scary is that you don't know if what happens really happened or if it was all in Harry's head. *shivers*
Title: The Darkness Takes Me by xonceinadream
Rating: PG 13
Pairing: Harry/Ginny, mentioned Ron/Hermione
Word Count: 5,134
Summary: Ever since the final battle Harry saw the shadows. He doesn't know what they're here for until he does.
Warning(s): Character Death, scary stuff
Notes: When Harry came back from that place he went after the killing curse, something came back with him, too. You see the warning, "scary stuff"? Yeah, scary... this fic is terrifying.
Title: The Final Sacrifice by teshara
Rating: PG 13
Pairing: James, Albus, Scorpius, Harry, Ginny, Draco, McGonagall, Hermione, Ron.
Word Count: 18,000
Summary: When James finds a hidden passageway in the castle he recruits Albus and Scorpius to help him. What they find, no one could predict. Hogwarts demands tribute, but can Harry stop it before it’s too late?
Warning(s): Character Death
Notes: This is a Gen story, mainly featuring James, Albus and Scorpius. Their discovery of a hidden part of the castle will change not only their lives and those around them, but the castle itself. The plot, the characterisation and the ending are absolutely brilliant.
Harry/Draco recs are @ my_drarry_recs.
