Amber Daulton

Revenge and love defy any marriage contract. Cartel princess Carlota Lozano has spent years living under a man's rules. Married off to a ruthless capo, she plays the trophy wife when the world is watching, a polished lie her unfaithful husband demands. After he sends their twin sons away to boarding school, the careful mask she's built begins to fracture. Then she meets her new bodyguard-the dark, irresistible man she'd drunkenly kissed at a party-and melts under his expert touch.
Tajo Aguilar wants to destroy his half-brother, the man who stole his future and now holds Carlota as his wife. She was supposed to be his leverage, nothing more. Yet she ignites in him a desire he can't control, twisting his vengeance into something far more dangerous. When her husband uncovers their affair, Carlota and Tajo must risk everything for a love destined to destroy them. - Book 4 in the dark romance series, the Lozano Cartel.
All the books can be read as a standalone, but are part of an interconnected series.
