Where's my Depth First Search Machine Learning? – Towards Data Science

My first thought after reading that sentence was: "Why didn't Amazon recommend me that book when I was buying Camille's?" Then I started reading the Three-Body Problem by Cixin Liu. In the first part of that book they mention another book called Silent Spring, which according to Three-Body, it seems to have been censored by the Cultural Revolution. Without spoiling the story, Silent Spring is a very important element inside the story, up to the point that later I realised the first part of the book is actually called Silent Spring. Inside Three-Body, the book Silent Spring is only mentioned by the characters here and there, and we realise it's important to know about it once we have gone through half the book. While it's not essential to have read Silent Spring in order to understand Three-Body, it seems like quite an interesting book to have. So while reading this I also wondered: "Why didn't Amazon recommend me that book when I was buying the Three-Body Problem?" Finally I've just started reading Nobel Prize winner Svetlana Alexievich's The Unwomanly Face of War, which is an account of the Soviet women that fought during WWII.
