So Be It. A Novel (en Inglés) - A. Lê

Carlos spent five years being humiliated by the woman he loved. He knew about the betrayals. He heard the short, dry laugh. He stayed.
Until a stranger named Laura looked at him and said two words: "Poor thing."
That night, Carlos left.
But leaving was only the beginning. Now he must learn to stay - for Laura, for her wounded daughter Ana, and for Bianca, the fifteen-year-old girl he never knew existed.
A raw, unflinching novel about humiliation, revenge, forgiveness, and the slow, painful art of not running away.
