This book is confusing to me. It should be right my cup of tea because of the subjects, however it makes me slightly uncomfortable, like it's a bit to earnest or something. The premise is very silly (why do the aliens make it sound like it's all the humans or all is bad?) but somehow despite it the arguments it makes as a result feel pretty realistic (because if a mother with children jumps into abyss you try to catch her or at least her children), and even educational (I didn't know about values-based decision making before this book). Overall, not my favourite book even though I feel like I should like it better.
