Seven thriller fans. One remote island. A dream retreat turned deadly.

Kalah loves her job as a poison control hotline operator. She helps strangers through the worst moments of their lives—without ever putting herself in danger.

But when she wins a contest from a mysterious new author, everything changes.

She and six other readers are invited to a secluded island in the Florida Keys for an exclusive retreat to preview the author’s debut thriller. At first, it's paradise—until the island’s caretaker vanishes without a trace.

Then one of her fellow readers disappears.

As the group searches for the missing people, Kalah’s paranoia grows. Soon, she believes that someone is hunting them—a deranged psychopath who could be hiding in plain sight.

To survive, Kalah must confront her darkest fears, outwit a killer, and uncover the truth before she becomes the next chapter in a real-life horror story.

Welcome to Isla Tumbas—where every page turned could be your last, and survival is the ultimate plot twist.

For fans of The Guest List and Final Girls, Reader’s Retreat is a chilling psychological thriller about isolation, obsession, and the price of survival.
