In the shadowed corners of West Sound, a lethal concoction of drugs claims its victims with ruthless efficiency—four lives extinguished in as many days.

Detective Jefferson Hughes follows the deadly trail. What starts as a seemingly routine case tied to the city's homeless population takes an ominous turn when a lifeless body surfaces in a wealthy golf course community.

Meanwhile, middle school teacher MJ Brooks senses a troubling change in one of her students. When the girl vanishes without a trace, MJ embarks on a personal crusade to uncover the truth. Soon her investigation intertwines with Hughes' pursuit, revealing a web of deception and danger.

In a reluctant alliance, Hughes and MJ find their paths converging once more. However, as the urgency to solve the mystery escalates, so does the magnetic pull between them, binding their fates in ways neither anticipated.

As the stakes rise in Book Two of the "On the Sound" series, their alliance may be the only hope of revealing a world where shadows conceal both truth and peril.
