Covert operator and former military officer Nathaniel Stratton has one focus, protecting his country. His dedication to his job means he has no time for relationships, and there's no place in his life for love. While he's home on leave, helping run the BDSM club he co-owns, Nathaniel is captivated by the vulnerable and beautifully submissive Alani Dane, one of his employees. For years, Alani has been hiding a secret. She trusts no one, and especially not the overbearing and tempting billionaire who is determined to earn her trust even as he destroys the fortress she's built around her life, and her heart. When things spiral out of control, and her worst nightmare is realized, Alani has no choice but to count on the persistent alpha protector. Will the price he demands be too high to pay?
