Easton Gray is sent from the future to prevent the end of the human race after nanotechnology spreads rapidly, leading to danger and disaster. As an operative for the Ministry of Discourse, Easton's only goal is to eradicate the technology.

Dr. Tess Nolan is alone, except for the company of her rescue dog, Lou. It's not until a stranger shows up in town and her life is turned upside down that she realizes the love she's been missing. Easton is everything Tess didn't know she wanted, but her warning bells are sounding. There's something too convenient about Easton's arrival.

Caught between her need to follow orders and her growing feelings for the beautiful doctor, Easton begins to question everything she knows, leading her on an investigation that will change not just her life, but the future as well. When forced to target Tess, can Easton do what's needed to save humanity? Or will finally finding the one person who feels like home prove impossible to ignore?
