Andromeda's Galaxy

Andromeda loved her sisters and her sisters loved her. They were her world. There were no secrets between them. Until Bellatrix met Rodolphus, and suddenly there were. And the more she tried to make things right, the more Andromeda realised that she didn't know what "right" was. And as she let others into her heart, she realised that maybe her world did not have to feel so small.
