It was good as a suspense, but the romance part didn't work for me very well. Reno was so rude and cold all the time, that I couldn't understand what attracted Jilly, besides his exotic appearence. And Jilly was supposed to be a kid-genious but never acted like one.
Still, it was fast paced, enjoyable and fun. Just not in parr with the others in the Ice series.
