I spent most of the first half of the book trying to picture in my head what the Fade looked like. They're shadows! They can chameleon themselves! They're super strong and smart! No.. wait.. they have human forms! They're strong.. but then they're not! They have tentacles! No, wait they have human-ish arms! They can shapeshift! Aghhh.. what??
To add to that one mindfck, though fascinating, the world is also a bit difficult to understand at first. Eventually, the plot kept me reading, thought I never really got too invested in the characters. I thought that the "hive" notion of the Fade was pretty cool though, and reminded me of [b:Ender's Game|375802|Ender's Game (Ender's Saga, #1)|Orson Scott Card|http://d.gr-assets.com/books/1364033163s/375802.jpg|2422333].
