The Darkest Stars - The Broken Stars, #2

The most terrifying monsters are the ones that lurk inside... After discovering everything she's ever known has been a lie, Calay understands humanity's brutality firsthand. Now, depleted rations, unexplained aberrations, and an ecosystem in collapse have driven her to the brink of madness-even with Jacob by her side. When a mysterious woman sent from the stars promises to grant every desire Calay's ever locked away in her shattered heart, she's forced to make an impossible decision: remain on a dying Earth or journey to a planet two-billion lightyears away in an effort to save them all.
Clinging to the dream she might yet find somewhere to call home, she agrees. After all, how much worse could it get? When she arrives on the shimmering, glass-city planet Téras, Calay desperately want to believe in a better future. Despite being haunted by the past she'll never escape, her hope is buoyed by the reunion with the mother she thought long-dead and the possibility of uniting their civilizations.
The reality, however, is more horrifying than anything she could have imagined. As the universe descends into darkness, she finds herself trapped in the far reaches of deep space, face to face with dangerous forces, unyielding truths, and feral monsters that will force her to confront the darkest parts of herself, pushing her to the very limits of what it means to be human. In this gripping queer sci-fi odyssey, Calay's journey through love, betrayal, and self-discovery becomes a fight not only for her life, but the survival of Earth itself.
