Shadow’s Doom By Mary Stone

Ice cream, you scream
Welcome to my murder scene.

Sheriff Rebecca West and her team may have ended the Yacht Club’s debauched reign, but things on Shadow Island haven’t calmed down. In fact, it’s taken on a more terrifying form. Sensationalist headlines accuse Rebecca of everything from conspiracy to corruption, but the real danger isn’t in the ink and whispers. Something worse has washed onto the shores of Shadow Island.

And it can kill in a single bite.

A local man has fatally overdosed on fentanyl at the ice cream parlor after polishing off a salted caramel cone. No history of drug use, no needles, no signs of addiction—only a body filled with poison. Rebecca suspects something far worse than a tragic accident. But how does fentanyl find its way into a dessert?

When a father and his two children are poisoned by fentanyl after eating at a local diner, Rebecca comes to a startling realization. A sadistic killer is playing a dangerous game of chance, turning routine moments into fatal traps. The island is no longer just haunted by its past—it’s under siege by a faceless killer, lurking in every bite, every sip, every breath.

Instead of a bullet, he’s randomly placing poison around town in a deadly game of Russian roulette. No one is safe. And any unsuspecting citizen could be next.

Shadow’s Doom, the horrifying seventeenth installment of the Shadow Island Series by Mary Stone and Lori Rhodes, is proof that the power to kill is the most addictive—and deadly—drug of all.
