Secrets has Harry in love with Umbridge and with Hermione (with whom he breaks up); he also flirts with Draco, but I couldn't tell how serious that was.

Marvin in Love is about a Mary Sue for Marvin the Paranoid Android.

Secrets (crossover) has Hermione taking Teddy Lupin, who isn't going to Hogwarts because Hermione (whose marriage with Ron has been childless and annulled) is afraid he'll be a bully magnet, to "Barrow man Road [sic]" where they meet the Jacksons (and Hermione carries Alan's child). Oh, and Hermione has stolen Molly Weasley's moment of glory.

Better Than Revenge has Time Lady!Hermione, aka the Destroyer. She gets it on with the Saxon Master, who is now contemporary with the Harry Potter books.
