DC Comics novels - Harley Quinn: Mad Love

I really enjoyed about 3/4 of this book. I am not a Harley Quinn fan. I have never been a Harley Quinn fan, but it was interesting to read about her life as a child and as a psychiatrist. I had a problem with a certain section in the book that was added for no other reason but for a politically correct inclusion of a certain type of person. I have no problem with inclusion, if it was important to the story. This section that was added served no purpose and was unnecessary to the story, since the character does nothing to advance the storyline. It felt forced, it read as forced and it almost turned me off to the rest of the book. I did finish it and was disappointed in Harley's transformation in the end. I give it 4 stars because the first 3/4 of the book was so interesting enough to warrant that rating.
