Broken Guard. The Colman Brothers, #3

He was never supposed to fall for his best friend's fiancée. When restaurant manager Zach Colman meets Maya Sinclair, she's captivating, guarded, and completely off-limits. Engaged to a powerful heir with ties to one of South Africa's most dangerous crime families, Maya insists they're only friends. Friendship should have been enough. As months pass, boxing matches, late-night conversations, and an unexpected lockdown bring them closer than either of them ever intended.
Behind Maya's perfect smile is a controlling fiancé, a ruthless father who refuses to let her escape the family empire, and a future that was chosen for her long before she had a voice. Zach knows crossing that line would destroy lives. Maya knows staying where she is might destroy her instead. With loyalty tested, dangerous families closing in, and feelings neither of them can ignore, they'll have to decide whether love is worth risking everything.
Sometimes the hardest person to protect... is the one who already owns your heart.
