   Summary

   Coming home is the worst part of Sirius Black's year.

   Grimmauld Place is as suffocating as ever, his parents are unbearable, and every room feels determined to remind him exactly where he comes from. But when the house is suddenly empty, Sirius finds the one reason he came back instead of escaping with James Potter.

   At Hogwarts, Regulus Black is untouchable. At home, behind a locked bedroom door, he's something else entirely.
