Hard Glass by Lina Langley

All Mason Payne wants to do is keep his head down and quietly age out of the system, but when he has to step in to defend his foster sisters against a terrifying foster father, his life takes a turn he never imagined.
He’s placed with loving foster parents. People who should make him forget about everything.
Instead, they make him run right into his past.
And his past isn’t at all what he imagined.
His past is exemplified by Jules Dubois, practically Mason’s reflection.
And while Mason is aware he should hate him, Jules is hard to hate.
He’s nice. Very nice.
And untouchable.
No matter how much Mason craves him.
No matter how much he wants to touch him.
…Right?
