Query: Best in Class

Having traveled over much of the world, I am not a newcomer to this type of book. I think this is the most comprehensive, best written book of its class that I have come across. My husband and have been considering retirement in Costa Rica (even more so since the recent election) and Ms. Van Rheenen answered every question we had thought of and some we hadn't. Her knowledge of the culture, history, geography, health care, etc. is obvious and I would recommend this as an essential read for anyone traveling to or thinking of living in Costa Rica
