Rollback

Rollback
by Robert J. Sawyer (2007)

This is the first Robert J Sawyer book I read. Having now read all of his books, this is one of his best and recommended for anyone entering the science fiction genre and wanting a near-future and realistic scenario.


Dr. Sarah Halifax decoded the first-ever radio transmission received from aliens. Thirty-eight years later, a second message is received and Sarah, now 87, may hold the key to deciphering this one, too… if she lives long enough.

A wealthy industrialist offers to pay for Sarah to have a rollback—a hugely expensive experimental rejuvenation procedure. She accepts on condition that Don, her husband of sixty years, gets a rollback, too. The process works for Don, making him physically twenty-five again. But in a tragic twist, the rollback fails for Sarah, leaving her in her eighties.

While Don tries to deal with his newfound youth and the suddenly vast age gap between him and his wife, Sarah struggles to do again what she’d done once before: figure out what a signal from the stars contains.
