Tied to Him: The Billionaire's Beck and Call, Book Three: A Dominant/Submissive Romance (Volume 3)

This is the third book in the Billionaire's Beck and Call Series, but can also be enjoyed as a standalone. 

Becoming Governor isn't in the cards for billionaire and former D.A. Jackson Pierce unless he can squelch the unsavory rumors flying around. He's not ashamed of his bad boy past being a dominant at a BDSM club, but he knows the revelation could ruin his political career before it even begins.

He's skeptical of his campaign advisor's idea--find a do-gooder wife to give him a more respectable image--until he meets Rose Turner, a former foster kid working in a local community center. Compassionate, feisty and passionate about helping troubled youth, she's perfect for his needs. But as they get to know one another, his feelings for her grow all too real. 

Rose Turner can't take another heartbreak, not after being abandoned by everyone she ever loved. When she accepts Jackson's proposal, she vows to keep her distance, but the more she gets to know him, the more she wants to let him in. But trust doesn't come easy--if he wants it, he'll have to earn it. 

What's a man of principle to do when everything he believes in falls apart?
