The Loneliest Girl in the Universe
by James, Lauren
Romy Silvers is the only person on the spaceship Infinity, drifting through the dark void after the death of her parents. Her entire life is dictated by strict protocols and the occasional delayed video message from Earth. When she learns another ship, the Eternity, is heading her way to join her mission, the prospect of companionship shifts into something far more unsettling. This is a claustrophobic psychological thriller that plays with the fragility of a mind shaped by total isolation. The pacing is deliberate, turning every small sound or glitch on the ship into a source of mounting dread. You never quite know if Romy is seeing the truth or if her loneliness has finally frayed her perception of reality. It is a perfect match for readers who enjoy character-driven tension and stories that force you to question the reliability of the person telling the tale.
