Great story - could have used more science fiction or just a more expansive treatment of the issues. That said, I could not put this book down.

The alien aspect of the story is really secondary and not explored very deeply - almost treated as an afterthought. While the deeper dive into the implications of medical advances that extend the human lifespan were intriguing from a social sciences perspective, I was really expecting more of a science fiction story.

As with other novels by Mr. Sawyer, this book provokes some deep thoughts while entertaining at the same time. Many interesting ideas are considered regarding morality and ethics while concepts and possibilities of science and the future are posed. Personal feelings about life as a human being are casually mixed with exciting notions about alien life and our place in the universe. This book starts a little slow, as we get to know the main character and the basic structure of the story is laid out, but fans of science fiction; for that matter, fans of open-minded thinking, will not be disappointed. It’s a fun quick read. Michael Travis Jasper, Author of the Novel “To Be Chosen”

Almost four decades ago back in 2010 astronomer Sarah Halifax, closing in on her fiftieth birthday, translated the first known message from outer space. She was part of a team that in turn provided mankind¿s response back to the Sigma Draconis aliens¿ radio transmission. --- Now she is eighty-seven years old when the second message arrives. She is elated, but knows it is too late for her or her spouse of sixty years Don to work the second message. However, robotic technology billionaire and SETI supporter Cody McGavin offers the elderly Halifax couple a chance when he buys a promising untested allegedly Fountain of Youth rejuvenation treatment for them to try. Sarah and Don do, but ironically though she is the key player, he is the one to ROLLBACK the clock to his twenties. Sarah works on interpreting the response while Don feels euphoric and guilty about feeling and looking younger than his grandchildren. --- This is an exciting science fiction thriller that focuses on ethical questions pertaining to relationships between a couple and between two ¿pen-pal¿ species. The story line is cerebral as Don and Sarah continue to be there for one another yet his needs have changed while she, though disappointed by her failure to regain her youth, prays for one last hurrah in which she will leave behind a legacy of doing what is best for humanity and for those sentient beings sending radio messages from Sigma Draconis, but how to know what is appropriate remains difficult to validate. --- Harriet Klausner

This book caught my attention as soon as I started to read. First it was because of the interesting notion about 'talking' to a star that is 18.8 lightyears away, but then it moved to intense when 87 Don and his wife get the rollback procedure but it only works for him. Seeing how their dynamic changes because he is now once again physically 25ish is interesting. In the background the moral/ethical questions by the Draconians and finding out their message drives you to read as well. Gunter the robot was my favorite character.
