I have found this to be a fantastically helpful reference book for everything Monteverde-related. This book isn't meant to be a best-seller, it (seems to be) designed for the subset of people who are interested in Monteverde, Costa Rica. If you have spent some time in Monteverde, or plan to, it has pretty much everything you could ever want to know about natural history and climate. It is also put together in an easy and intuitive manner, which counts for a lot when you are trying to find one specific thing in a book that is about everything. It is aimed more towards science, but it also has quite a bit about the history of the town. This is the first place I would look for helpful tidbits of information about Monteverde like yearly rainfall/mist, neat graphs that break down the number of species of plants of various life forms ("X% of plants in MV are climbers, Y% are epiphytes, Z% canopy trees"), and the such. I would strongly suggest it to anyone interested in Monteverde natural history. This is not a field guide, it won't help you identify anything to species, but it will be a very good supplement to pretty much any field guide, so you can see what ever you are interested in the large framework of its ecosystem.
It is also just plain fun read.
