I have never read a nonfiction book before, but I couldn’t put this one down.

This book brilliantly highlights the conflicts the SeaWorld trainers went through on a regular basis. Taking care of these highly intelligent beings they have formed an intense relationship and trust with, while also realizing that the orcas living conditions are unsustainable. 
The author talks about the way orcas live in the wild, painting a stark difference to lives and behaviors of captive orcas. It was distressing to read about the painful medical procedures necessary because of their self-destructive behavior. What SeaWorld put those orcas through, as well as their trainers, who often destroyed their bodies trying to make the animals life better for laughably little pay, was horrifying. 
I was already a Sea Shepherd supporter and had seen The Cove and Blackfish, but I still learned lots of new information and I hope I will someday be able to see these fascinating animals in their natural habitat.
