Heart of Obsidian
by Singh, Nalini
Kaleb Krychek has spent his life as one of the most feared and cold-blooded members of the Psy race, but he has been hiding a secret obsession for years: Sahara Kyriak. When she finally reappears, damaged and holding the keys to his darkest impulses, the power dynamic between them shifts violently. This is not a gentle romance; it is a collision of two broken, immensely powerful people trying to survive in a society that demands perfection and emotional suppression. The pacing is relentless, fueled by Kaleb’s terrifying competence and Sahara’s fragile, recovering psyche. You will feel the weight of their shared history on every page. If you enjoy high-stakes paranormal settings where the heroes are morally gray and the love stories are forged in fire and absolute, unwavering devotion, this book will ruin you in the best way possible.
