Freefall by Mindi Scott
How do you come back from the point of no return?
Seth McCoy was the last person to see his best friend Isaac alive, and the first to find him dead. It was just another night, just another party, just another time where Isaac drank too much and passed out on the lawn. Only this time, Isaac didn’t wake up. Convinced that his own actions led to his friend’s death, Seth is torn between turning his life around . . . or losing himself completely. Then he meets Rosetta: so beautiful and so different from everything and everyone he's ever known. But Rosetta has secrets of her own, and Seth will soon realize he isn’t the only one who needs saving . . .
