The Summer Guests by Tess Gerritsen

New York Times bestselling author Tess Gerritsen returns with a pulse-pounding follow-up to The Spy Coast, plunging the beloved Martini Club into a web of secrets that refuse to stay buried.

When a teenager vanishes from the quiet coastal town of Purity, Maine, former spy Maggie Bird finds herself drawn back into the shadows she thought she’d left behind. Her neighbor stands accused, and Maggie knows the truth is far more complicated than it appears. With the Martini Club—her circle of cocktail-sipping, ex-CIA confidants—by her side, she’s determined to prove her friend’s innocence.

But this is no ordinary missing persons case. The discovery of a decades-old corpse in a nearby pond sends shockwaves through the investigation, connecting present-day danger to long-buried secrets from the spies’ own pasts. As young police chief Jo Thibodeau navigates her uneasy alliance with these retired intelligence operatives, the pressure mounts from the victim’s powerful family demanding answers.

Gerritsen masterfully weaves together two mysteries that collide with devastating force. Her signature blend of sharp suspense and richly drawn characters creates an unputdownable thriller where every revelation raises the stakes. The seaside setting becomes its own character—beautiful and treacherous, hiding darkness beneath its picturesque surface.

Perfect for fans of espionage thrillers with heart, The Summer Guests proves that retirement is never truly an option when your past comes calling. The Martini Club must race against time before more lives are lost to secrets that demand to be told.
