"A startling, fascinating novel." - Kim Stanley Robinson, New York Times bestselling authorIf we can alter the structure of reality, should we? In Observer, scientist Robert Lanza, one of Time Magazine's "100 Most Influential People," is joined by Nebula and Hugo Award-winning author Nancy Kress to confront the space between biology and consciousness. 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. Joining a fascinating and relatable cast of characters with a mind-expanding journey to the very edges of science, Observer will thrill you, inspire you, and lead you to think about life and the power of the imagination in startling new ways.
