My excitement demands the prospect of mid-tk-flight kisses and I wasn't promised that, so... :P (again: joke, I have a weird sense of humour)
I don't think the book is going to be a train-wreck, really.
I think it's more on the lines of being able to spend time in a non-pandemic New York City with all its museums, shows, theatre plays, operas, ballets, cinemas, night clubs, bars, parks, shops, restaurants and end up going back to the Green Lagoon, to get drunk with the same people, listening to Dazzler. Again. :P
I do hope we come back and talk about how amazing the book is and how we never read a better version of Jean Grey.
