Ka: Dar Oakley in the Ruin of Ymr (John Crowley)

With the exception of a brief framing story set in a climate-torn near future, this book is told from the perspective of an immortal crow who learns to communicate with humans. The book is structured around three major relationships that Dar develops with a prehistoric shaman, a medieval monk, and a Civil War widow. Each one gets an extended section of the book where you both see human society through a crow's perspective, and you also see how Dar himself is changed by his relationships with humans.

While I found the plot compelling, the best thing about this book is Crowley's delicate and subtle handling of Dar's non-human perspective. Crowley asks us to take the more-than-human seriously in its own right, while showing how it is intertwined with human choices. I've read a lot of academic work arguing for this approach to the Anthropocene, but Crowley's book makes it come alive through language, character, and story.

Note that the book is quite long, but you can read each time period separately and take breaks in between if you prefer.
