Ace. Castle Sin, #4

One castle. Ten Masters. And a secret that could burn it all down. A tale of misguided intentions, regret, and lies. Three years ago, Remy Torres threw Ace Sinclair's marriage proposal back in his face and walked away. Now the DEA needed her to protect him from the Chinese Triads-and she'd rather face a firing squad than the man who hated her as fiercely as he'd once loved her. Ace-Master Leo to his submissives-had nursed his grudge into something darker, sharper, hungrier.
and it had her name carved into it.. The moment Remy walked back into his world, the beast inside him stirred. So did the lust her infuriating innocence had always sparked. He should have thrown her out. Instead, the dark beast in him smiled. Desire, revenge, and regret made vicious bedfellows. With bullets flying and Stone's life on the line, Remy and Ace danced a deadly tango of jealousy and longing.
If only she could swallow her pride.If only he could learn to trust again.
