The Cousins

Karen M. McManus delivers another high-stakes, twist-filled standalone mystery in The Cousins. Milly, Aubrey, and Jonah are cousins who barely know one another and have never met their fabulously wealthy, reclusive grandmother, Mildred Story. Decades earlier, she abruptly disinherited their parents with a single cryptic letter stating: "You know what you did." So when all three cousins receive an unexpected summer invitation to work at their grandmother’s exclusive resort on Gull Cove Island, their parents urge them to go, hoping it will repair the family rift and secure their inheritance. However, upon arrival, the teens quickly realize that their grandmother didn't send the invitations—and someone else is pulling the strings. As they delve into their family’s dark past and search for answers about the event that tore their parents apart twenty-four years ago, the cousins uncover a dangerous web of deception, long-buried secrets, and betrayal, proving that the Story family legacy is far more lethal than they ever imagined.

It offers a fast-paced, addictively bingeable mystery filled with rich-family dynamics, multi-generational secrets, and shocking plot twists that keep you guessing until the final revelation.

Ideal for readers of YA crime and mystery fiction, fans of suspense stories involving rich family drama and island settings, and admirers of Karen M. McManus's bestselling catalog.
