World-spanning battle blah blah blah forces Tony Stark to confront his deepest fears: loss of control, catastrophes where he seems only able to do more damage, drinking again, an irrational and supernatural universe. Gripping, although I could have done with less about the grumpy dwarves. The developing clash between Bethany Cabe and Pepper Potts is intriguing; I'm looking forward to finding out where Pepper is going.
