Overgrowth

Overgrowth by Mira Grant 

Overgrowth by Mira Grant is a gripping blend of alien invasion thriller and full-on body horror, perfect for fans of Invasion of the Body Snatchers, Annihilation, and Day of the Triffids. With razor-sharp suspense and chilling sci-fi realism, this apocalyptic horror novel explores what happens when the warning signs have been there all along—and no one listens.

Anastasia Miller has been saying it since she was three years old: she's not human. She's an alien left behind on Earth, waiting for her true family to return. For most of her life, people dismissed her claims as fantasy, delusion, or a cry for help.

They’re not laughing anymore.

Now, strange signals are coming from deep space—heard across the globe, interrupting communications, driving people to madness. Something is stirring. Something is growing. The world is finally realizing the truth: the invasion has already begun.

As the Earth is overtaken by an otherworldly plague of spores, parasitic growths, and biological transformations, Stasia must face the truth of her identity and the terrifying purpose of the "family" coming to retrieve her. But she's not a helpless child anymore—and the reunion might not go the way anyone expected.

Terrifying, intelligent, and deeply unsettling, Overgrowth is a must-read horror novel about identity, survival, and what it really means to belong—when the ones who claim you want to consume everything you are.
