What are the motifs in The Alchemy of Race and Rights by Patricia J. Williams?

Williams seeks to both defend the critical theory approach to law and to critique it. She accepts the movement's basic theses and emphases but wants to amend its spirit by recovering rights-talk to raise the marginalized and the oppressed. However, while Williams' book is a work of legal philosophy, it hardly reads like one. Instead, The Alchemy reads more like an autobiography with news items thrown in for good measure. Only occasionally does Williams make her arguments explicitly and in principled terms and aim them directly at the reader. Instead, her arguments are often left to reader interpretation from the stories she tells and the conversations she recounts.
