Leave the book behind.
Dull, plodding, and over padded despite it's slim 241 pages, this book reads like it was written by a student desperately trying to meet a minimum word count.
With it's family vacation goes bad premise the suspence never builds. Everyone is just present. Sick kid? No terror. Lost kid? No panic. Living with strangers cut off? No problems.
Adding the banality of the sheer nothing that is the story and writing, the author has some peculiar fixation with aging sex, armpit sniffing, and describing people being horny. If it happened once it would have been enough. But it occurs multiple times and adds nothing to the story.
Skip this forgettable, bland, dud.
