Perfume is the story of a plain, quiet girl named Dove who buys a bottle of "evil" perfume under an influence not quite her own; when she does so, her evil twin, Wing, is unleashed.
When it starts out, "The Perfume" can't decide if it's going to be a complex story about a girl with emotional problems, or a horror story about good and bad both fighting to win; the beginning is a bit of a drag.
Beging a die hard fan of Caroline Cooney's, I thought it would be a great addition to my collection and a good scary read, however I was kind of dissapointed in it because unlike with her other horror books (The Stranger, The Mummy etc ) the plot never sucks you in deep enough and seems kind of stupid in the end. Definatly not Cooney's best work.
Bottom line: if you love horror in any way, shape or form, or Caroline Cooney, then buy. Otherwise don't waste your money.
