I don't know why this took me so long to read. I found the book sort of slow to get going, got like a third of the way through, and then got distracted by the idea of re-reading Chris Claremont's entire Uncanny X-Men run. Then I picked this book back up and burned through the remaining two thirds in a day and a half.

Anyway, with more granular ratings, I'd give it three and a half. I do think it starts off sort of slow, but it picks up very quickly. I dig the slow motion apocalypse taking place just outside the boundaries of the story, and the way it mirrors Jane's personal situation.
