I volunteer for a wildlife rehab center, and love working with the turtles. This Sy Montgomery book on turtles is really about turtle rehab and about the pandemic a little bit, but mostly turtles. I love her writing because she does hands on work and research and then makes them very readable. In this book she works with a turtle rehab in Massachusetts, and learns about what turtles face in the wild and how they are both tough and fragile. She also visits a facility where extremely endangered turtles are raised, saves cold shocked sea turtles on Cape Cod, and learns about different measures for protecting turtles. Several times she talks about people not caring for turtles properly. Montgomery doesn't flinch away from terrible injuries and illness and doesn't sugarcoat things... anyone familiar with animal rehab work won't be shocked, but this might not be for everyone. 

One thing that I thought was fascinating is that she talks about how turtles perceive time, including their inability to see fast things, like cars. A car driving looks to them the way a hummingbird wing looks to us.
