Twelve-year-old Leslie Adams is found covered in blood, standing over the lifeless body of a boy named Tommy. Everyone said she did it—after all, she was the only one there when he died. The most terrifying part? Leslie doesn’t remember a thing.

Years later, she still can’t escape the shadow of that day. Now in college, Leslie is desperate for a fresh start... until the blackouts return. Night after night, she wakes from these fugue states with fresh bruises and unexplained cuts on her skin. Doctors insist she’s self-harming—coping with repressed trauma. But deep down, Leslie knows something far more sinister is at play.

Disturbing visions begin to haunt her: echoes of childish laughter in empty rooms, the silhouette of a familiar little boy lingering just out of sight. Leslie fears the horror that claimed Tommy never really left. With each missing moment, the darkness inside her grows—stronger, bolder.

And when the truth finally claws its way to the surface, Leslie must confront a reality more terrifying than any childhood nightmare. Because the real horror isn’t what she might have done back then... it’s what’s been hiding inside her ever since.

"In “Little Brother,” Cosco has crafted a masterwork of biological horror that reads as early Cronenberg filtered through a contemporary lens. It’s a nerve-shredding, at times terrifying debut that forces us to confront the ultimate betrayal – when the enemy isn’t just within, but is quite literally part of our own flesh and blood."
