Despite its title, Truth of the Divine is not a religious text, but a fun, fast-paced, clever science fiction adventure. It’s the second book in the Noumena (also not a great title) series. The first is Axiom’s End, and you should read it first.
In this alternate-history first-contact yarn, the government continues to be run by jerks, and the one person the aliens are talking to is a snarky, blue-haired young woman, and all the guys in charge HATE that. Of course, the aliens have their own Alien Issues to deal with, but those are now spilling over to affect the rest of humanity, and all indications are that everything is going to get worse.
