Brother by Marina Vivancos

Nathan had always loved his twin brother. How could he not? They had been inseparable since before birth. They’d shaped each other. Were each other’s homes.
But even love, Nathan knew, could go too far. Too deep. So he had tried to keep his distance—had gone to a different college, tried to make a life without his brother.
Now that they’re both back home for summer, though, Nathan doesn’t know how to escape the way he feels…or the way his brother might feel in return.
