Adam Rutherford skillfully puts together an overview of the history of eugenics and influence of eugenicist ideology on modern science. The book is accessible without feeling overly simplified, and there are many quotable sentences. I learned new-to-me nuances on basic genetics, various scientific experiments and eugenics in other countries.

There were a few points at which I would’ve appreciated more depth/examples and more connection to modern social narratives on genetics, health and ableism. 

Compelling, insightful and eye opening. Not scared to get technical or describe the science, but eminently readable and accessible to a lay reader like me. 
Facts are stated clearly, the author recognises his own biases and is able to introduce humour, appropriately. 

Not too dense, but always introducing new ideas to consider and challenge. Love the acknowledgment of the author's own biases.
