Supersonic

It's Harry's seventh year. The second war is raging, but at Hogwarts, a new girl suddenly arrives. Snape acts weird around her and Harry keeps wondering where he has seen her before.... Strange events take place. Dumbledore has a special plan and Aunt Petunia has something to show Harry. Lucius is facing rough times as both his son and his former friend Snape have something to tell him. And to top it all, Voldemort is trying to take over the Ministry. How is Harry going to save the Wizarding world and his own life? Does he even care after losing too many people he loved?

Remus is visiting Sirius at Grimmauld Place during OotP. He's not feeling well, recovering from his tranformation. But he wants to tell Sirius something. Cute/sad slash story.
