The Beast's Nanny. The Nannies, #7

When Grace pays for a customer's breakfast, she assumes she's just doing a favor for a miserable man. But he repays her by kidnapping her. Before he took her, she was living a normal life, worrying about bills and money. Now she's a nanny for his nephew, the cutest little boy she's ever met. Caleb Raine is a beast, having built his reputation from the ground up. All he knows is betrayal and pain. On one of the hardest days of his life, Grace is a beacon of light.
He wants her, and he's used to getting what he wants. She's everything he's not used to-a woman who cares, who loves. When he offers her an ultimatum, he expects her to reject it. For a year, she'll be his personal fuck toy in exchange for her freedom. He doesn't expect to crave her or need her. Taking her is easy. Keeping her is even easier. Falling in love with her, though, that's not part of the plan.
