How To Be an Anti-Racist was not what I expected when I picked it up, but I still got a lot out of it. I, like I'm sure a lot of people, expect a book that is instructional in anti-racism. Instead, I found it to be essentially a memoir, describing Kendi's own path to anti-racism as a Black person, starting with his understanding that despite being Black, he held racist ideas against Black people. As a White person reading the book, this is a very interesting script-flip, to have the Black person talking about their own internalized racism and path away from it. 

The book is a great blend of anti-racist education, with each chapter talking about the institutions and spaces where systemic racism manifests, perfectly blended with his own life story. Readers (or listeners, as I was) are pulled along and prompted to our own self-reflection of examples of racism in ourselves and in our lives as Kendi describes his own self-reflection. A story that I particularly connected with was one he opened the book with: a speech he gave at a contest that was racist, although he didn't realize at the time -- it was well-received by the mixed-race audience.  It caused me to reflect on the times I've expressed racist views, usually with a hefty dose of white fragility, without retribution-- because our societal understanding of "racist" is equated to white supremacy, not the milieu of stereotypes, biases, and microagressions we all perpetuate in a mostly White society. 
I think everybody could gain a better understanding of systemic racism and anti-racism from this book, but it would be especially good for somebody early in their social justice ladder. Many of the examples of systemic racism that Kendi describes would be well-understood by somebody farther up the social justice ladder, but they were well described and thorough for all to understand. 
People looking for actual instruction in anti-racism should check out So You Want to Talk About Race. I think these books are complementary, as this book helps you get into an anti-racist frame of mind, and inspires you to act, and "So You Want to Talk About Race" helps you act by describing concrete tips and advice on talking about race, while also further describing systemic and individual racism.

I listened to the audiobook via Libro.fm, which is narrated by Kendi himself. He did a good job, his voice was easy to follow and very clear throughout.
