It's not a great change for me to read stuff like this out of sequence, I remember growing up with the same issue when I was younger. This is the third book in the sequence, issues 13-18 and I hope to catch up with the rest of the story later. This is a story centering around Emma Frost and an invasion of the X-Men's campus by the Hellfire Club, it's an interesting look at how people can be broken!
Quite an interesting look at the characters and relationships within the group. Some of them really do need help! Kitty Pryde is a great character and several scenes pivot around her and her abiliities.
