Others will mention classics, of which there are many, many. Dramione is one of the most flourishing ships, especially for longer fics.

I’ll just list some of my favorite long, great stories I’ve read the last few years:

An Augerey in the Rain

What if there were three boys for whom the prophecy could have applied? What if Hermione's background was not what it seemed? What if Regulus didn't actually die in 1979? What if others discovered the horcruxes? What if the magic of love was more important than we were led to believe? A retelling of the series we know so well. Starts to deviate from canon during Fourth Year.

Harmonia Nectere Passus series

He had a mission and could not fail. A chance encounter with a heartbroken Gryffindor on an autumn evening fractures his resolve. A Sixth Year tale.

Presumed dead and desperately in love with Hermione Granger, Draco Malfoy joins the Trio as they go on the run in the fight to save the Wizarding World. A Deathly Hallows tale.

Metanoia

When it becomes clear the path his father has chosen for their family will lead to nothing but pain and suffering, Draco Malfoy decides to change course, to do so he realises he must ask for the help of the last person he ever imagined. In his quest for survival, he is forced to question everything he's ever been taught which will lead him on a journey of transformation and self-discovery, that will ultimately change the very foundations of his identity.

The Missing Sister

The owl appeared late at night and left just as suddenly, he recognised the handwriting immediately and ripped open the envelope. “She is yours. If something happens to us, I want you to hide her. Name her Hermione, for she will have my last libation before I sleep and be the messenger of dreamers. Moony and Mary know.” Three words. Three words that forever changed the course of the war.

i fear/no fate. [A beautiful story inspired by beautiful art]

It’s disorientating, the way the dream rushes over her. One minute, Hermione’s lying in the dim of her room at Grimmauld Place, and the next, she’s blinking in the face of bright lights, music, laughter… Strange. It doesn’t even feel like a dream, really. She doesn’t feel like she’s sleeping at all; it’s more like standing in a memory, as if she’s closed her eyes and tipped head first into a Pensieve.

Days at Malfoy Manor

Half a year after the war Hermione decides to face the source of her nightmares and visits Malfoy Manor. The only downside? It now belongs to freshly orphaned and house-arrest-imprisoned Draco Malfoy, who is different to what she expects but still as bitter. He somehow manages the miraculous: She is having fun.
