I know, I know, it's part sci-fi, part fantasy, so suspension of disbelief is a given. But I really had to exercise mine and consequently found the book so frustrating. I wanted to like it but it never really took off for me - all the bare bones are there; good idea for a plot, obviously well researched, potential for a well-paced story line...
The character of Dominique was a real problem; where the intention is for her to appear torn or confused she instead comes across as feeble. Where she is supposed to be strong-willed and feisty, she sounds whiny and annoying. The relationship between her and Mick has no chemistry and at times seemed completely unbelievable. One meeting and Dominique agrees that Mick is paranoid and mentally ill, the very next meeting she's back on his side again! Her constant prevarication throughout the book becomes quite tedious.
The pure sci-fi parts of the book were quite entertaining. The best parts were the excerpts from Mick's Father's journal, which demonstrates the excellent research that Steve Altern undertook for the story. I'd rate the book as average - a great idea for a story but the main characters weren't developed enough and there was a touch of 'James Patterson-itis' - i.e. trying to cram as much action and different plot-lines into the book and consequently only skating over each one, instead of focusing on quality rather than quantity.
