Thalli has fifteen minutes and twenty-three seconds left to live. The toxic gas that will complete her annihilation is invading her bloodstream. But she is not afraid.
Decades before Thalli’s birth, the world ended in a nuclear war. But life went on deep underground, thanks to a handful of scientists known as The Ten. Since then, they have genetically engineered humans to be free from emotions in the hopes that war won’t threaten their lives again.
But Thalli was born with the ability to feel emotions and a sense of curiosity she can barely contain. She has survived so far thanks to her ability to hide those differences. But Thalli’s secret is discovered when she is overwhelmed by the emotion in an ancient piece of music.

As her life ticks away, she hears rumors of someone called the Designer—someone even more powerful than The Ten. What’s more, the parts of her that have always been an anomaly could in fact be part of a much larger plan. And the parts of her that she has always guarded could be the answer she’s been looking for all along.
Thalli must sort out what to believe and who she can trust, before her time runs out…
