Its a good book, but not one of my favorites. The Sprung/Delbeek series are better IMO, and for just basic identification I always like the book titled something like "Corals" identification by Srung/Delbeek (Its a shorter book, not really part of the three book series).
As mentioned, the Sprung/Delbeek books titled "The Reef Aquarium" are my favourite references available.
The first book (there are three) deals with general aquarium setup, water chemistry, stony corals and clams. The second book deals with anemones, corallimorphs, and soft corals. The third is an updated reference guide - it deals with new topics...the earlier books were written in the mid-nineties.
I've never found better books for coral identification and care.
