Despite being short in length, "A River in Darkness" is a really heavy and difficult read. This is an educational story of one man's journey to and from North Korea, following propaganda offering paradise when they arrived. If you're not up to speed with this aspect of history and (even more sadly) the current political climate, I'd recommend picking this up.
For the most part, "Reaching Down the Rabbit Hole: Extraordinary Journeys into the Human Brain" is a really engaging, interesting and educational read. The conditions that are described are fascinating, especially from the doctor's perspective, but I couldn't really warm to the doctor or his outdated opinions. This one gets 3 stars from me.
