Wicked Heat - Wicked Nights, #4

From the moment he'd seen her at the home of his billionaire father, former race car driver and bad boy Ashton Stone craved Bree Bernstein, his half-siblings' stunning nanny. He couldn't have her though-not when his life was so entwined with secrets and scandal. Then he'd seen her at the airport bar and instead of walking away, he'd bought her a drink. Then another. And when a storm grounded their flights, he'd made a mistake and tried to take her to bed.
That's when she'd bolted. For years, Bree has hidden the truth of those nightmarish days when she'd been held captive, forced into despicable acts that, once rescued, she'd believed were in the past. Until the tapes. Now, she's being blackmailed, and if those tapes go public, it won't be just her life that's in tatters, but that of an innocent child caught in the crossfire. Desperate, she goes to the only man who can help her pay the blackmailer and keep the secret-Ashton Stone.
Now, her future is in his hands-but the price he demands is one she's not certain she can pay-Her.
