She's betting it all on the future... Celia Calthorp, Duchess of Acaster, is sick of always being on the edge of disaster. Now that widowhood has finally given her the freedom to make her own choices, she knows exactly what she needs to do-marry a rich man to secure her future and that of her beloved stables. And it's all going to plan...until it isn't. He never takes a risk he can't win... Gabriel Siren, proprietor of London's most exclusive gaming hell, knows exactly where he stands-always on the fringes of the aristocracy. That changes when he becomes the Seventh Duke of Acaster and inherits a beautiful dowager duchess, too. But Celia might be exactly what he needs... All bets are off when the gamble is love... Working together to secure his sisters' place in society, neither is prepared for the pull of attraction they feel-or being swept away when passion flares. As sweet as falling in love for the first time is, Celia knows that it can't last. But Gabriel isn't ready to let her go. Can he convince Celia to risk it all...for him?
