This was a hard book to read! It is riveting and informative, but so upsetting. Though the author tries to be balanced, contacting Sea World and other orca captivity supporters for interviews, the book it very anti-captivity. I don't know if the sensationalism (not sensationalism as in exaggeration, but sensationalist in tone) of some of the events covered is due to this bias or simply to the authors writing style. Either way, it really brought the plight of captive orcas home for me. More upsetting, for me at least, was the recognition of names, both of Sea World's whales and Sea World San Diego's trainers. I remember most of the births at the San Diego park that happened during my childhood. I only remembered one of the deaths. Reading this book has definitely made me look back on my hundreds of Sea World visits over the course of my life, and colored them. It's going to take me a while to move past this reading.
