It was OK
I was hoping this was linked to what happened in Generation Hope #8, but sadly it does not appear to be. We do get to see how M-Day has affected some former mutants, and that's neat. We also get to see why Wolverine acts so strange around her. (Although an astute reader probably already guessed why) This issue felt like a very fast read and I wasn't left as satisfied as I've been with recent Gillen works. Oh well. You win some, you lose some.
