Sofie Waits. Coffee and Donuts, #2

Amber was Sofie's first friend at a new school and they've been inseparable ever since. She's been the source of countless laughs and occasional dares. She supported Sofie through college and carried her through her mom's battle with cancer. But if Amber is her rock, Austin is Sofie's hard place. He's the only guy she's ever loved. She can't tell anyone because he's also Amber's brother. Sofie has spent eleven years trapped between her feelings for Austin and her loyalty to Amber, who would be horrified to find out about those feelings.
Now something has happened, something that means Sofie's feelings for Austin are no longer a secret. Sofie can't avoid the fallout forever, and it might not be anything like she expected.
