"Pleasant surprise"
This is SF with a new twist to my knowledge. Enough universe, consistent textures and story telling to satisfy the hard SF'er. At the same time Catherine brings in the human side. It is not very complex and still quite mono-dimensional, but this effect creates a very interesting and captivating tension in the layer that supports the story.
"Really depressing"
The worst book I listened to over the past three years. Guaranteed to worsen your mental condition especially if you are already feeling depressed. If you enjoy craving over the futility of life over a set of futile pages, this is something for you. "Read by the author" did not help. There should be a health warning on the package of this one.Make sure to hear a sample before you buy. The authors' voice, style and tone is totally in line with the content.
"SF with a literary twist"
Quite a few books have been written serving the underlying objective to make us ordinary mortals get used to the new perceptions of reality which the 20th century has imposed on us.
Where SF has been serving the general purpose to make us get more familiar and comfortable with change, it traditionally focuses on the machine/space/technology dimension, or it stays within the framework of myth/allegory. The time-traveler's wife is the first fiction I have encountered that meshes the SF factor so strongly with the human angle of the more traditional literature.
This is similar to but also very different from "Einstein's dreams" as Alan Lightman imagined them, admittedly quite a mind opener and entertaining book in itself. The Time Traveler's Wife is a much stronger synthetic story about the human condition in Einstein's universe. Highly original and overdue as a further development of the genre. Weird but recognizable, because close to the every day realities as we know them". Captivating beyond pure entertainment levels.
I would not recommended the story to the hardened cyber-enthusiast, but for those who meander between the believe that the modern insights into the fabric of reality should not be ignored and the nagging realization "all of that" does not appear to make much sense, may be surprised by this book.
