I liked the other mysteries in this series better, mainly because this wasn’t as logically constructed. (spoiler) For example, since the characters were not supposed to contact the police but obviously did and the “bad guys” knew it, why didn’t they keep working with the police? Second, why is it appropriate for the good guys to keep letting folk die, only caring about the cousin? Once it was clear that there were going to be a host of deaths from the sabotage, how was is appropriate for the main characters to not involve the federal authorities just to save one cousin? That’s outrageous. Finally, it was bothersome that characters called them snow mobiles in the book, when Alaskans seem to call them “snow machines.” I think it could have been a better story.
