To save her brother from a $200,000 gambling debt to the Montreal underworld, disciplined executive assistant Elizabeth Stone must agree to a high-stakes charade: spending a week in France as the fake lover of her ruthless boss, Henri Gagnon. Known as the "Shark of Montreal," Henri is a titan of industry who hides a protective heart beneath a cold, "obsidian" exterior. ​In the opulent corridors of Lyon, Elizabeth must navigate a world of corporate sabotage and fake romance to help Henri reclaim his father’s lost legacy. As the line between professional duty and "primitive hunger" begins to blur, Elizabeth realizes the greatest risk isn't the debt she owes—it’s the heart she’s about to lose to a man who always gets what he wants. This is a story of sacrifice, self-reliance, and the dangerous price of protection.
