I need help finding story

Looking for a story I found interesting but didn’t get the chance to add to “my favorites”. The MC name is Phoebe and she runs into a girl named Dana from her past. Dana almost died because of Phoebe and so Phoebe had to disappear from Dana’s life.
I didn’t get far so I don’t have much more info other than I believe there’s also a character named Silas that works with Dana
