The first of two books, Intelligence Taskforce being the second one, United Nations draws on elements previously seen in the series, bringing in members of the Russian and American military and or intelligence community, setting up a situation that once again will require international cooperation to resolve.

There's nothing in this one that's actually about setting up UNIT, but there's certainly a good deal done to sow the seeds. Actually, whenever the subject is mentioned, it's clear that the idea is met with a ton of resistance.

The plot of this book itself revolves around people who affect the laws of probability. I know I've seen this idea used somewhere before, but darned if I can remember where. In any case, it's handled well here and makes for some really compelling action. This plot is not resolve in part one, but it does reach a good, logical stopping point, setting up the action to be picked up in another location in part two.

I like how Fiona is handled here too. It's a little tough, as we know enough about Alistair's life to know that their relationship won't last, so it's bittersweet to see how much good there is in their relationship.

If there's one downside to the book it's that the focus on the international elements means that we don't get so much time with the series regulars (other than Lethbridge-Stewart). A necessary evil for where this two-book journey needs to go.
