Well, I guess I wouldn't say to avoid it. But it's not actually a book: it's a very clever string of quotes from the writings of Freud and Lewis. And the prose is not very smooth prose or well organized, which is annoying. Basically it's a substitute for thinking about the ideas of Lewis and Freud on your own; but since most of us don't have good enough memories or enough time to read all (or even most) of the works of those two thinkers and compare their works, it's very handy. Especially as I'm writing a paper on CSL's response to Freud. Very handy.
