I really enjoyed this book and it was quite easy to read. It is really a series of vignettes about different organisms that are either recently extinct or about to go extinct, and the scientists who study them. The author made me feel as if these creatures were friends that are slowly (or quickly in some cases) dying and there is nothing that can be done. In fact, that is my main objection to the book. She doesn't discuss solutions in any way, except very general approaches against climate change and that only in passing. It left me feeling particularly hopeless.
