This may well be the final book I read in 2015, and that's fine. It's a great way to end the year. I had the great good fortune of working with/for the author when he was traveling and writing his first book, Cool Creatures, Hot Planet, and I got to read that book as it was being written, a work in progress. I feel a bit of a tie to this new book in that I helped Marty's company a bit while he took one of the trips described herein--the Costa Rica 30th Anniversary Trip. As a matter of full disclosure, I should state that the author gave me an autographed copy of Endangered Edens with the understanding that I would write an honest review of the book. That is not hard to do. Marty's writing is such a pleasure to read, even when he's talking about dreadful places (Prudhoe Bay, anyone?). Reading Endangered Edens, I felt as if I were along for the trips involved, which is saying something in that of the four places described in this book, I have been to only one--the Everglades. Alaska and Costa Rica are on my bucket list, and now, having read about Marty and Deb's adventures in Puerto Rico, I certainly wouldn't mind going there in person. Marty's photographs are stunningly beautiful, even if I don't share his interest in herps (reptiles and amphibians). I would recommend this book (and the author's first book as well) to anyone interested in good travel writing, good adventure writing, great photography, and, perhaps most important, to anyone at all interested in the fate of our beautiful planet and what steps we can take to ensure that our children, grandchildren, and generations to come can enjoy it the way we have.
