He has everything—except control over her. She has everything to lose—except the choice to want him. Ace Carter built his empire on discipline. As the ruthless billionaire behind Carter Industries, he’s known for taking what he wants and never waiting for permission. Desire has always been simple. Temporary. Controlled. Until Mia Sanchez. Mia is warmth where Ace is steel—untouched by his world, guarded by her own fears, and quietly powerful in ways he never expected. Their attraction is instant, undeniable, and dangerous. But when Ace learns the truth about Mia, he does the one thing no one believes he’s capable of. He stops. What follows is a slow burn fueled by restraint—stolen moments, unfinished touches, and a tension that tightens with every breath they share. Ace wants her, but he refuses to rush what matters. Mia wants him, but choosing him means stepping into a world she’s never known. Because patience isn’t weakness. It’s devotion. And when Mia finally decides she’s ready, Ace knows there will be no holding back—only the kind of connection that changes everything. The Billionaire’s Restraint is a seductive billionaire romance filled with longing, emotional intimacy, and explosive chemistry—perfect for readers who crave protective heroes, innocent heroines, and passion that builds until it breaks.
