I'm perhaps being unfair by only rating this one 3 out of 5 - the pros, the plot, the characters are all as vivid as any Sawyer novel I've read to date.

the trouble I found with Rollback (apart from the title reminding me of a supermarket commercial) was that I never quite clicked with the main character. yes, I feel for his plight, and I cannot help but swoop through the emotional depths - so it was a good, solid read. But for me at least it lacked the pace of Flashforward and the intrigue of Frameshift. Enjoyable, but nothing to fawn over.
