This seems to be the best guide to the Azores available, and it does provide good coverage of the islands (we visited 6 of them). But the guide desperately needed someone to do some substantial sub-editing, since the author seems not to have the slightest idea of how to organise his material to make this guide book easy to use.
Many places/attractions were described in two different places, such as once under the island and once under the town, or once in the main text and once in a separate section with shaded background. The index was fairly good, but one could see the poor arrangement by the fact that so many places have two or three disjoint sets of page numbers by them.
The maps often showed places to visit that were not described at all in the text, and vice versa. Opening dates/times were often not shown - maybe these quickly get out-of-date, but it would be nice to have had them there while the guide was new. Most town maps had no scale - many said "not to scale" but actually from comparison with maps we got there, and with our own experience, they were pretty much to scale, it just wasn't stated. The descriptions of walks around towns would have been good, had it been possible to follow them on the maps - typically most of the streets named in the text could not be found on the town map. I could give numerous examples, but that would make this review too long.
In summary, we found this a very frustrating guide to use. Actually we have found this before with Bradt guides - coverage good, organisation terrible - I guess they simply don't feel it necessary to make any improvements to the text sent in by the author. Pity.
