I was more than a little disappointed with this, the final novel in the Repairmain Jack series. The preceding two novels were all building up to this one, supposedly the final denouncement, but it left too much up in the air to be the finale (and Wilson stated in the intro that Repairman Jack plays a large role in the next book on the timeline). I know Wilson has a lot of other books in the 'Secret History' urban fantasy world he has built, but to really make sense of this one, I suppose you would have had to have read others outside of the Repairman series. Also, lots of anecdotes emerged in this one regarding Jack's childhood, which seemed like a plug for another series of his and did not add much to the plot.
So, the 'One' is set for endgame, lining up all his ducks in a row. Can the 'fabulous four' of Jack, Weezy, the Lady and the former Ally champion stop him? The 'One' knows (heavily alluded to from either another short story or novel) that the champion is mortal and very aged, giving him a free hand to act-- e.g., to bring on the otherness. Knowing this, the champion gives Jack the green light to try to take out the 'One', but first, Jack has to find him...
I will not say more as that would entail spoilers, but Wilson does at least thin his main characters down a little. As usual, good action sequences and flowing prose, but after all the build up to this one, I expected a lot more. 2.5 stars rounding up.
