I haven't read such a bad book in a while. The plot was far fetched, too fragmented, and unlikely. The characters - especially Jane - unsympathetic. The interaction between the characters is psychologically a stretch.
But what really bothered me was the repetitive writing style. "She stiffened", "he stiffened", "Trevor stiffened", "McDuff stiffened", there was a lot of stiffening going on - in lieu of interesting action, obviously.
Everyone is angry and constantly saying "dammit". Jane's gaze flies a lot. Her gaze flies to his face, flies to the action, flies here and there. And she whirls. "She whirled on him" - frequently. McDuff whirled a few times, too.
Between the stiffening, the whirling, the gazes flying and the dammits, the style was insipid to the point of torture. Needless to say, I do not recommend this book.
