The Unknown by Riley Sager – Hardcover Thriller, First Edition with Hued Edges

Riley Sager's instant #1 New York Times bestseller: a struggling actress joins a film about five women who vanished from a Vermont island in 1926, and a century later it starts happening again. Deluxe first edition.

In 1926, five women disappeared from New Avalon, an island commune for spiritual mediums on Lake Faraday, Vermont. The only trace left behind was five dresses hanging from an old oak tree, one for each missing woman. Some locals say they simply left. Others believe a séance gone wrong, recorded in the diary of a young medium named Daisy Rue, summoned something that took them one by one.

One hundred years later, struggling actress Marin Keane lands a role in a major film about the unsolved mystery, and learns that the job requires a week-long research trip to the island itself. Soon after she and her castmates arrive, the island's past begins to repeat.

The first edition of this stunning hardcover features designed endpapers, a foil-stamped case, hued edges and a shimmering jacket, making it a standout on any shelf. A must for fans of Riley Sager's twist-filled, page-turning thrillers.
