SCENTIENCE by Tylar Pendgraft
After scientist Deborah volunteers her Air Force captain husband, Josh, for a genetic alteration that will make him a better soldier, he is involved in a training accident that leaves another soldier dead. As Deborah and Josh attempt to recover from this tragedy, she discovers she is unable to carry a child to term and turns to science to remedy the problem. The results are life-changing and terrifying. Sentience is a chilling science not-so-fiction tale redolent of "Black Mirror."
