A breakthrough in human cloning becomes one woman’s waking nightmare in a mind-bending thriller by the Wall Street Journal bestselling author of the Gibson Vaughn series.

In the near future, advances in medicine and quantum computing make human cloning a reality. For the wealthy, cheating death is the ultimate luxury. To anticloning militants, it’s an abomination against nature. For young Constance “Con” D’Arcy, who was gifted her own clone by her late aunt, it’s terrifying.

After a routine monthly upload of her consciousness—stored for that inevitable transition—something goes wrong. When Con wakes up in the clinic, it’s eighteen months later. Her recent memories are missing. Her original, she’s told, is dead. If that’s true, what does that make her?

The secrets of Con’s disorienting new life are buried deep. So are those of how and why she died. To uncover the truth, Con is retracing the last days she can recall, crossing paths with a detective who’s just as curious. On the run, she needs someone she can trust. Because only one thing has become clear: Con is being marked for murder—all over again.

This was a twisty, fast-paced sci-fi thriller that I didn’t want to put down. It explored the ethical and moral dilemmas associated with cloning. I enjoyed the way the author framed these discussions about what constitutes personhood and how to ensure the new technology would be used for the good of all and not just the elite. The world-building was also very interesting, and the author’s take on what the political landscape and environment might look like in the near future left me contemplating how we could avoid that future. The writing was simple and easy to read, and the pacing of the story kept ratcheting up the tension at every turn. I loved the character of Constance and getting to see her thoughts as she struggled to come to terms with being a clone. This book kept me guessing for quite a bit, but I did eventually figure out the surprise before it was revealed. The ending felt a little over the top and seemed like the easiest answer to all the mysteries, which is one of my biggest pet peeves when it comes to thrillers. Overall, though, I enjoyed the ride, the author’s interesting take on the future, and the ethical and moral implications of the work. Therefore, I rate the book 4 out of 5 stars.
