Product Description

From Publishers Weekly

Starred Review. Canadian author Sawyer (Mindscan) once again presents likable characters facing big ethical dilemmas in this smoothly readable near-future SF novel. Astronomer Sarah Halifax, who translated the first message from aliens and helped prepare humanity's response, is 87 when the second, encrypted message arrives 38 years later. To aid the decoding, a tycoon buys rejuvenation treatment for Sarah and Don, her husband of 60 years; however, only Don becomes young again. While coping with the physical indignities of old age, Sarah tries to figure out the puzzle of the second message. The bond between Don and Sarah continues, even while Don is joyfully and guiltily discovering the pleasures of living in a young body again. They want to do what's right for each other and the rest of humanity—for the aliens, too—if they can figure out what "right" could be. By its nature, a story about moral choices tends to get talky, but the talk is intelligent and performed by sympathetic and believable people. Sawyer, who has won Hugo and Nebula awards, may well win another major SF award with this superior effort. (Apr.)

From Booklist

Sawyer's latest concerns the reply to a message sent 38 years previously, responding to an alien radio transmission. Sarah Halifax worked on the team responsible for translating the original received message, and clearly she may be vital to the second. But she and her husband have just celebrated their sixtieth anniversary, and neither expects to live much longer. A hyperwealthy benefactor offers to pay for her to have a rollback, a somewhat experimental rejuvenation process, and agrees to another for husband Don, too. The process works for Don but not for Sarah. While Don struggles with second youth, Sarah continues translating the message. Sawyer's investigation of rejuvenation--especially difficult for a man with the body of a 25-year-old married to an octogenarian--and of massively time-delayed communication with aliens loads a fascinating story with difficult issues. Don makes mistakes, yet he and Sarah are good people and thoughtfully constructed characters. Rollback exploits two staple sf tropes to produce a nicely executed, human-scale story. Regina Schroeder

5.0 out of 5 stars Biological time machine, May 2 2007

By	Stephen A. Haines (Ottawa, Ontario Canada) - See all my reviews (TOP 10 REVIEWER) (REAL NAME)

One of science's more frustrating endeavours has been the quest to find other intelligent species. Dolphins and whales communicate with squeaks, while chimpanzees and orang utans use tools for various purposes - usually dinner. This is doubly tantalising - humans aren't all that unique, but neither of these lifeforms offers much in the way of philosophical dialogue. The Search for Extra-Terrestrial Intelligence was founded a half-century ago to search elsewhere for somebody to talk to. The search was among the stars.

In this well-conceived and executed tale, Robert J. Sawyer has speculated on the possible results of "listening in" on the Cosmos. A major problem in interstellar communication is that distance equals time. If a planet circling a star 18.8 light years distant wants to chat, it's 37.6 years between responses. SETI had triggered a "first contact" which was translated by Canadian astronomer Sarah Halifax and a reply transmitted. Now, nearly four decades later, whoever lives near Sigma Draconis has answered back. For some reason, the "Dracons" have encrypted the message. Sarah is in her eighties, yet it's clear that she's the best candidate to deal with the new message. At her age can she cope with the intense labour involved in the exercise?

Help is at hand from the science studying aging. An entrepreneur interested in SETI has agreed to fund the means to extend Sarah's life so that she can work on the encrypted message. Sarah, and her husband Don will have their aged bodies "rolled back" to a more youthful physical age. It's like starting life over with almost endless possibilities. The "rollback" process, though tried on only a couple of hundred people, is "foolproof". But while it works on Don, it fails on the person needing it most - Sarah.

Sawyer examines the many practical and philosophical issues surrounding the possibility of extended life. The first, and most obvious, is where Don's restored libido might lead him. Another aspect is the realisation that age may bring wisdom, but what is its worth in terms of employability. Moore's Law says computer power will double every 18 months. Translate that into terms a man retired for twenty years confronts when he seeks a job. Rollback is an expensive process - not everybody can afford it. How does a man deal with his children who are "older" than he and that he's certain to outlive? These are the types of questions Sawyer has a superlative talent in posing and addressing. His ability to develop real characters who must deal with such issues is without peer. Underlying these capabilities is a firm foundation in the relevant sciences. "Rollback" may be speculative, but only in the narrowest definition of the term. Sawyer didn't place this story only a generation in the future just to avoid extravagant surroundings. The science he depicts is almost there. Only the Dracons are missing . . . [stephen a. haines - Ottawa, Canada]

For nit-pickers: The question of how Don's brain, which has been adjusting to his advancing years, would react to the sudden reversal of the remainder of the body's effective age to 25. Whatever the results to his libido, there's as good an argument for his going insane as there is for Sawyer's scenario of the resetting of his chronological clock. Yet another philosophical question raised by this excellent author. - sah

5.0 out of 5 stars Mind and Body, April 9 2007

By	Friederike Knabe (Ottawa, Ontario Canada) - See all my reviews (TOP 50 REVIEWER) (REAL NAME)

You have to be a certain age before you will consider whether you want to be young again and live youre a second time. Sarah and Don are octogenarians and, after a full and contented life with children and grandchildren, have options to change their lives that we rarely dream of. However, Sarah, Dr. Halifax, is not just anybody. She is a well-known scientist who, back in 2009, had deciphered the first message from Sigma Draconis, a star system some nineteen light years away from Earth. Now, thirty-eight years later, the response to Earth's message is received and nobody can break the encryption code. Can Sarah do it again and will she live long enough to make it happen?

Cody McGavin, chief of a robotics company and always on the lookout for new technological discoveries is one the richest people around. He is convinced that Sarah is vital to decoding the message now and also for future message exchanges with "her Dracon pen pal". It is 2048 and, thanks to a process of DNA resequencing and some other "tuck" jobs, it has become possible to literally roll back a person's biological body to the prime of their life, around age 25. The procedure is experimental and only for the super-rich, like McGavin himself. He is willing to pay for Sarah to have this chance at another lifespan. It's not something she accepts lightly, insisting that her husband of 60 years, Don, is included in the offer. They both undergo the procedure which is successful for Don but not for her.

While in Sawyer's previous bestseller, Mindscan, life could be extended thanks to copying a complete brain map onto the bionic body, in Rollback advances in medicine are the solution. Here the ethical question is not so much who is the real person, but how do you harmonize an octogenarian brain with a 25-year old physique? Can you relive your life without stumbling over history? How do grandchildren deal with a grandfather who is much younger than their own parents? How do friends and former colleagues react? And, above all, how does this gap influence the relationship between husband and wife? Can it survive at all?

Leave it to Robert Sawyer to pack his speculative fiction with deep philosophical questions and topics for debate. Rejuvenation is but one of these. If humans can recreate themselves to live, maybe forever, are humans in fact playing God? How do people and societies cope with that? Cosmic communication is another major theme. The first message that Sarah had decoded was in effect a detailed questionnaire about Earth's peoples' perspectives on life and society. Why do they want to know? What do you tell aliens about human society? Do you tell the truth or do you present Earth in the best light possible? How to answer moral and philosophical conundrums? The range of the Dracons' questions probe deeply into the human psyche, testing its integrity.

The narrative moves between timelines of 2048, to previous milestones in the couple's life, mostly through Don's pondering his memories. There was Sarah's work with the SETI (Search for Extra-Terrestrial Intelligence) project that led to the first transmission from Earth into the universe. Her discovery of the code that deciphered the Sigma Draconis message and the complex organization of the reply. Don, a TV and radio producer for the Canadian Broadcasting Corporation (CBC), was a good and patient dialogue partner for his wife. Through their conversations, played back in Don's mind, the reader can follow multiple strands of arguments about the worth of SETI, astronomy, genetics and more.

Sawyer has referred to Rollback as a "phi-fi" novel - a philosophical novel. The book's events are strongly anchored in current scientific knowledge. It speculates on possible future scenarios in fields like medicine and inter-stellar communication. Yet, this is also very much a human interest story. Sawyer has created memorable characters and realistic environments in which their lives unfold. It will fascinate the fan of Sawyer's sci-fi books as much as the general reader who is interested in a well written story that raises questions some of which we might pose ourselves already today.

5.0 out of 5 stars Personal, Jun 6 2008

By	C. Crewson (Calgary, AB) - See all my reviews (REAL NAME)

I disagree with the 2/3 star review, but I am biased. This is perhaps the most personal book that I have ever read. My character, personality, and opinions were so in-sync with Sarah that I felt this book was perhaps the most personal I have read. That being said it makes me the most Biased reviewer possible, as reading the book was not an exercise in fiction, but self search. I have convinced the people in my family who read continually to read this, to better understand me.

To those of you looking for true science fiction, Asimovian in nature I would highly recommend it

Rollback is the kind of sci-fi where smart people talk talk, with hard science and little fantasy, and no laser blasters. Read more
