Fall or, Dodge in Hell

The world-building in this book is crazy good. I found myself getting lost in Bitworld and the Quest often. My only real gripe is how the ending was reached. I didn't really understand half of the battle, which is partly down to having a hard time grasping the layout of the location Neal has created. But the most disappointing thing to me was the ending of El's story. I thought it was anti-climactic and should/could have been one of the best parts of the book.
Despite all of that, it was a great book and I wouldn't hesitate to recommend it.
