The Book of Lost Fragrances

I pre-ordered The Book of Lost Fragrances because I'm a HUGE fan of Rose's Butterfield Institute Series; I was severely disappointed. First, the book's "pace" was extremely slow making it a drag to read. I put it away several times and purely on principle "if I bought I'll read it" was I able to finish it. Second, the premise was interesting and could have been quite alluring, if not for the main character's , "Jac", continuous denial of spiritual-esoteric things and acceptance of  "being crazy" instead. Third, the ending seemed to be put together very quickly, as if suddenly realizing the book has taken way too long and its time to get to its conclusion. However, this is done at the expense of developing more of the positive quality of the book, the idea that there is a fragrance that will allow individuals to view their past lives in order to correct mistakes in their current lives and fix their karma. Because of this quick wrap up, the book's conclusion is quite disappointing and leaves a feeling of "that's it????". Also, I never read anything about a BOOK of fragrances...it was more of broken shards of pottery that were infused with the hallucinogenic fragrance...since 32BC.
