The swamp holds the darkest secrets

Only they dare to uncover.  

Intent on solving her mother’s murder, Monique Santori travels deep into the bayou in search of clues. Encountering Jacque LeBlanc is a surprise as he casts off his self-imposed seclusion to help Monique find the killer. When Monique is attacked in a bid to stop her sleuthing, she finds herself safe in Jacque’s home. Though Monique is unwaveringly drawn to the mysterious loner, she understands Jacque’s past is off-limits. He’ll help her find answers, even protect her with his life, but she fears he’ll never give her what she truly desires.
