I admit: I read this book by accident. A friend recommended the Angelfall series to me, so I downloaded these books from Amazon and read them quickly before I realized I was reading the wrong books. But I'm glad I did.
The story mostly follows Aristotle who lives in Dante's version of Hell and happens to have been placed in Limbo, where he grows restless. Aristotle begins to explore the lower levels of Hell, where we encounter the Hell that Dante describes. Why is he wandering? Well, that's the rub... because this story is broken into three parts (not three books, but one large book published in 3 parts) we don't really find out yet. Unfortunately, part 3 seems to be where we get some answers and it hasn't been published yet (the last page of book 2 says that book 3 will be available December 1, 2011 but it is currently December 22, 2011 and it has not been published yet).
I liked part 2 better than part 1 - I think because we actually start to see some ACTION. Part 1 was largely about scene-setting and getting to know the characters. One small note is that there are a LOT of characters with a lot of Greek names that can get a bit confusing at times (although generally the names are a little on-the-nose "Mortuus" is the dead guy, "Militus" is the military guy, etc.) when trying to remember which person belongs to which group. I read that this story series came from a pitch for a video game, which is an interesting concept but also to that end, I was surprised that some of the "battle" types of scenes were hastily written and seemed... I dunno... to cop out at the last second? No spoilers, but suffice it to say that we come across 'slapping the beast on the nose stuns it and it realizes that it is wrong to kill people' types of tropes. Especially with a videogame type of background, I would have expected the fight scenes to involve lots of details of complicated actions.
Again, this book just ENDS and leaves you waiting for the third installment. Also, as other reviewers have pointed out, there are a quite a lot of grammar and spelling errors that took me out of the story and prevent me from giving a 5/5 rating.
