While overall I found Small Great Things a compelling and engrossing novel, I had some qualms about the POV voices, and felt that the message, important as it is, sometimes got in the way of the plot. (My full review is here.) 
 So far, the Picoult novels I've read all have a dramatic twist at the end, and this one does as well... and it seemed really unnecessary to me. (view spoiler)[ Finding out that the white supremacist mother was really half black doesn't add to the story at that point, and felt like sensationalism for the sake of shock value. (hide spoiler)] 
 Still, it's a good, interesting read, even though the courtroom drama aspects could have used more attention.
