He decodes monsters for a living. She’s the only target he can't read... and the one woman he'll burn the world down to keep.

Deputy U.S. Marshal Silas "Rook" Jensen doesn't make mistakes. As Task Force 9’s elite psychological profiler, he dissects human behavior down to the millisecond, hunting the world’s most dangerous syndicate: The Consortium. Clinical, detached, and relentless, Rook reads targets in micro-expressions and body language. His current objective? Track down Dahlia—a cold, calculated operative who just smuggled six captive girls across the Myanmar border.

Dahlia moves through the shadows with an iron composure, wearing her armor like a second skin to survive inside a brutal criminal underworld. She doesn't break, she doesn't flinch, and she doesn't leave a trail. Rook expects a monster. He doesn't expect a woman whose cold reserve is an impenetrable fortress.

When Rook corners her in the treacherous borderlands of Southeast Asia, an operation detonates into chaos, forcing the hunter and his target off the grid—and into tight quarters on the run. Surrounded by enemies and hunted by the very syndicate she serves, Dahlia is the ultimate enigma.

Trapped together across riverboats and hidden safe houses, their lethal cat-and-mouse game explodes into dangerous, primal obsession. Rook was trained to analyze her every move, but the longer he stays near her, the more his clinical distance turns into terrifying, possessive protection. As the line between enemy and ally blurs, Rook will break every rule he’s ever lived by to keep her alive—because once he claims her, he is never letting her go.

Lethal Deception is a dark-edged romantic suspense featuring an elite profiler hero, an unreadable heroine, forced proximity, possessive protector obsession, and a guaranteed happily-ever-after.
