X-Men Legacy: Divided He Stands - Mike Carey

The story starts of slow with the great mutant leader Professor X getting killed which involves a bunch of characters I don't know and don't want to know, but the story become more interesting as it gets grounded as the professor has to reestablish his own history and uncover some hither to unknown truths about his own and his friends' lives. That is where I get caught up in the tale and shortly thereafter the comic ends. I have to look for a sequel.
