Not too bad as tinnitus books go
Tinnitus books generally contain the same info, and since there really isn't a "cure" for this malady, you're going to get a lot of the same general advice from most books (that's been my experience anyway). This one takes off on a different tangent towards the end, which might be useful for some. I think it's worth a look but I wouldn't go out of my way to get it.
