Ash Harbor is the kind of coastal town that wears its charm like a mask—quaint, quiet, and full of secrets. Perched above the cliffs, the historic Morran House Inn welcomes a wave of summer guests for a lavish wedding. But when the bride's enigmatic cousin, Lila Monroe, vanishes during a sudden storm, the celebration turns into something far more sinister.

Eve Morran, the inn's sharp-eyed owner and a retired intelligence officer, knows something isn't right. Lila's disappearance feels too familiar, echoing the town's whispered legends of Widow's Point—a cliff where women have gone missing for decades.

As Eve pulls together her old "book club" of former spies, she begins to unravel a conspiracy stretching back to the Cold War. Buried files, forged identities, and long-silenced betrayals resurface, pulling the town into a web of espionage and murder. And when a second body is found beneath the cliffs, Eve realizes the past isn't done with Ash Harbor—or with her.

In a race against time and history, Eve must expose the truth before someone else vanishes... or worse.

Gripping, atmospheric, and razor-sharp, The Summer Guests is a slow-burning thriller where every secret leads to another—and nothing is what it seems.
