(3 to 3.5) 
 I'm not completely hooked yet, but I can definitely see the appeal, and it won't take long. 
 I love the world-building, for starters, and I'm pretty sure that what I've seen is nothing compared to what's to come. I'm also quite impressed by the balance between "show" and "tell": nearly all we know of the characters is through their actions and their words, while essential information is provided by the narration, which is quite interesting in and of itself. 
 On to volume two, then!
