Sombra De Sangre

She came for revenge. She found her brother. Chloe Vega survived the unthinkable-poverty, the loss of her family, and six years of abuse in the foster system. Now she's an FBI agent with one mission: bring down the mafia king who destroyed her life. But when she finally confronts the Don's feared second-in-command, she discovers a truth that shatters everything. The man known as "El Silencio" is her brother Austin-alive, transformed into a killer, and with no memory of her.
Now Chloe must make an impossible choice: destroy the empire that took everything from her... or save the brother she lost twice. Loyalty is everything. Betrayal is the only unforgivable sin.
