WHEN SHE DISAPPEARS, HE'LL RISK IT ALL TO UNCOVER THE TRUTH. Billionaire playboy Tristan Wagner has a secret: he's an Interpol agent on a mission to root out corruption. His latest mark? The captivating Lucia Oliveira, suspected of involvement in a twisted scheme within his family's company. What starts as a calculated seduction becomes an intoxicating affair. But when Lucia vanishes without a trace, he must confront a chilling possibility: either Lucia is the victim of a sinister plot, or she's been playing him all along. Racing against time, he'll break every law to find her.
But as layers of deception peel away, he uncovers shocking truths that threaten everything he thought he knew, leaving him with an impossible choice: protect his family's legacy or save the woman who's stolen his heart. Sinful Beauty, the third in the Beauty trilogy within the Arrow Tactical Series, is a steamy, suspenseful standalone romance full of heat, mystery, and adventure. AUTHOR NOTE: The Arrow Tactical Series is written so the books can be read without prior reading.
However, if you might want to read the earlier books in the trilogy--to avoid spoilers--start with Stolen Beauty.
