'Cloying' as a word tends to be used for things that are kind of sickly sweet. Oils used in diffusers, bad perfume or cologne, etc. could qualify. But it could also be physiological. Some people have conditions whereby they have a peculiar, pungent odor. Diabetics can smell sickly sweet, when their sugars are off. Ketoacidosis.
Other physical conditions can make your body odor smell like onions, like old fish... but when I hear 'cloying' my brain goes to sickly sweet, and I think diabetes.
But then you have people like Richard Ramirez, who didn't wash, and as a result, had an odor described as like 'a wild animal' and 'leather'.
MOO
EDIT: If you put the ISBN of that book in ebay, a handful of secondhand copies come up, so it's out there. Try ebay, try Abebooks. Both should have copies that don't bankrupt you. I wouldn't expect there to be a digital version. It looks cheap pulp, I doubt they forked out to put it on Kindle.
