Of Orcas and Men by David Neiwert
7 out of 10

Orcas are intelligent apex predators.  The relationship between their species and ours is unusual.  We can kill each other, but that rarely happens.  Since the 1960s, some orcas have been held in captivity.  Trainers and scientists have learned a lot about these magnificent animals.  And because they are multimillion-dollar assets, they are typically treated well.  Now, there are orcas born without ever knowing freedom.  Perhaps humans can maintain a healthy relationship with killer whales, but each one belongs with their family in the open ocean.
