Magick!
The second book focuses on a harder to relate too character, the Cross-dressing, trans-gender shaman, Lord Fanny. I know it sounds silly, but with The Invisibles silly at first can change quickly.
In this book Grant Morrison continues too teach us that the world is not what it seems. Magic is real and he goes into why it is in this book. It is a very interesting lesson of metamorphosis of Humanity and its ancient relationships to cultures like Egypt and India. Don't forget the Aliens as well!
It is impossible for me to write a long review without spoilers and without ruining the Invisibles experience. Make sure to not skip book 1 before reading this one.
Cheers!
