Moonrose

The Marauders use a rare type of Time-Turner to travel twenty years into the future. In that time, Lord Voldemort wants Abigail Black dead. He may try to kill Sirius to get his way. But when they lose the Time-Turner, they must go on a journey to get a new one led by Callista Lupin, Remus's daughter. But the one obstacle is that Remus falls in love with his own daughter.

Because of him, Sirius had died… Or had he? What exactly does the veil do? However, he most certainly would never see Sirius again, and Harry wasn’t about to let anything like that happen again.
