I haven't read any Katia Lief books before but the preview pages on this looked good.
I found it fairly well paced (except for a couple of places). The time constraint of the story, which is set over 24 hours, lends itself to sharp prose and by and large that worked OK. The plot is relatively simple, but there were some surprises, twists and turns. The dialogue was also OK, but just a little irritating sometimes and didn't always add to the storyline. Character development was fairly superficial. I felt there were opportunities to flesh out individuals and it would have added to the reading experience and plot.
It's an easy read; I finished the book in a little over a day of reading on and off. And at the end, I was left feeling that I neither fully enjoyed the book, nor intensely disliked it. I can't put my finger on the reason for this ambivalence; it's very much a what you see is what you get book. Certainly not bad enough to put me off the author and I will try another one by her. We shouldn't judge the value of a book based on the cost, but I don't regret spending a few pence to try out someone new. I'm not usually one to sit on the fence, but this is an average read.
