I couldn't find a whole review that included the first quote. I did, however, come across a lot of positive reviews that seem faked. As an example -- Bill Gates is quoted as saying that it was his "new favorite book of all time." That strikes me as incredibly unlikely, and I can only find reference to it on the same page on which I found the first quote.

Said page, and the quotes on it, have the breathless quality of someone reviewing their own fanfic while using an alt. Publishers regularly cherry-pick the best sentences out of reviews to put on the cover, but in this instance they seem to have gone way too far. It would not surprise me in the least to find out that the reviews were simply made up out of whole cloth.
