Yesterday I finished Rollback by Robert J. Sawyer.

Sawyer is probably the most prominent current Canadian SF author and he likes to use Canadian locations in his books to add colour. He also has a very laid back, casual style that is quite different from most other authors in the field.

Usually I like his approach, and I've liked most of his books a lot, but it doesn't work as well in his latest novel. The little touches of local colour seem more of a distraction from the main story. Also, the main story itself is less engaging than most of his novels. The main characters undergoes a rejuvenation procedure along with his wife, but it succeeds for him and fails for her. There is also a background story of first contact with an alien species going on at the same time, but the two plots don't integrate well and the novel seems to meander along before wrapping up where most novels would begin.

It's an interesting effort to address the effects of aging, and how a person would react to returning to their youth, but ultimately failed to move me.
