I've felt for a while now that this series has gone on for too long, but after the shocking events of the last book I must admit that I have been eagerly waiting for this one. Fallout is also an excellent title because fans of the series know that Rolo's shocking betrayal is going to result in King Xavier becoming an unstoppable force bent of revenge. X is old, and he is losing the support of many of those around him, but he is called The Immortal for a reason. Rolo thinks X is dead so he has no clue what his actions have initiated. Of course Rolo's betrayal was the most devastating event of the last book but it wasn't the only thing that went sideways. Michael has also been deposed as leader of the Vanguard Islands by Charmer and Roger is MIA after the fall of Outpost Gateway. It all adds up to humanity being on the brink of extinction but I don't really care about any of that, Rolo needs to die.
