Query: Thick book and out of date

We just got back from a Greek isles trip and this book was a big disappointment. Overall it was a blah assessment of the islands that did not differentiate good sites from bad. It also appeared to us that the Crete section had not been updated in several years as we found restaurants and hotels that the locals told us had been closed for a while but were given stellar reviews. It's too bad Rick Steve's doesn't have a Greek Islands book!
