Perry certainly isn't afraid to tackle any social subject. That is what drew me to start this mystery series. I was hoping for a good mystery that I didn't solve right away but have failed in that mission. What keeps me renting these books is Perry's unforgiving delve into social niceties.
For all of that, Defend and Betray went too far off the soapbox for me. Some subjects are naturally abhorrent to a rational human. They don't need attention drawn to them. While you may be trying to help the victims, you are just shining a spotlight on a behavior that could be given unintended consequences for all the attention.
The only redeeming factor to this book--after skipping chapters at a time when I figured out why Alexandra killed her husband--was the court scene at the finale. I was only too happy to have missed the unnecessary dissertation on the immoral acts of the Carlyon family as well as the always too lengthy rambling of Monk trying to figure out his amnesia.
