Ahh, I loved this. It was so delightfully boring, and I don't mean that in a derogatory way. I would feel so tranquil, so at peace and filled with inner quiet, every time I opened it. I learned a ton of new information, which I always enjoy, but also the author was able to teach me and lull me at the same time. It isn't funny, it isn't charming, it isn't riveting, but hot dog if it didn't completely win me over. I could be way off, but I get the impression that this guy is like the conservationist version of an engineer, and he delivered his information in as straightforward of a way as possible. And that may not sound winningly interesting, especially with our current trend of trying to write nonfiction that is as much like fiction as possible, but I loved it! And now I know so much more about butterflies. It is a miracle any of them survive, and I have a vastly larger appreciation for the science that goes into their conservation. It also made me want to help, which not all of these de-extinction series books have done, so I think he must have struck a fine balance between explaining the terrible predicament that butterflies are in and leaving room for hope that they may be saved.
