Falling With You

The day I lost my best friend was the day I realized that I'd been living in the past. I've tried to find a way to heal, to mend that break. Somehow, I came through it partially whole. But I know I couldn't have done that without Aiden Connolly.
The problem is, he once loved my best friend. And now she's gone, and I refuse to be in that shadow, or worse, a replacement for someone we both loved.
~~
I left them all behind.
My brother.
My family.
My best friend.
And her.
Only Sienna Knight doesn't realize what she means to me. But before I can make sure she knows, I need to figure out exactly what that is.
