Dr. Caroline Soames-Watkins's star has been on the rise. But when she accuses a superior of sexual misconduct, the Twitterstorm that follows upends her career. With few professional options and an impoverished sister with a disabled child to support, Caro is willing to consider a mysterious proposal from her great-uncle, the Nobel Prize-winning scientist Samuel Watkins. Sam Watkins has invested untold sums of money to build a medical facility in the Caribbean. But he is very sick and in urgent need of a surgeon to perform a unique procedure developed at his island compound. The procedure isn't for the cancer surely killing him. It is to offer new life of a truer kind. Helped in his mission by the eminent physicist George Weigert and the young, charismatic tech entrepreneur Julian Dey, Sam has gone far beyond curing the body to develop a technology that could solve the riddle of mortality for the soul. Though wary of the project's secret aims, Caro signs on for the chance to secure a future for her sister and herself. What she encounters is something so much more profound than she ever could have anticipated. It will put her on the precipice of a humanity-altering discovery. It will lead her to a level of interpersonal connection that she thought was only for others. And it will throw her into a kind of danger she never imagined.
