The ice must flow!

Yesterday, William Wright posted "Can Pharazon repent? AND a frozen egg up high on a wall," which as I suppose you can tell by the title is largely in response to my poem about Humpty Dumpty, in which Humpty stays up on the wall all through the fall and then freezes when winter comes. Having previously connected Humpty with Ar-Pharazôn, the last king of Númenor in Tolkien's mythology, William suggests that Númenor might now be something like Europa, the ice-covered moon of Jupiter, and perhaps might even be Europa itself.

This dredged up some vague memory I had of once having read a sci-fi story set on Europa, which I tried in vain to track down. In the course of my search, though, I discovered this book which I'd never heard of:

It's called Europa Affair: The Ice Must Flow (2017). The subtitle is presumably a punning reference to "The spice must flow," the well-known catchphrase from David Lynch's 1984 Dune movie, but it also happens to be uncannily relevant to William's post.

In answering the question in his title, William suggests that Ar-Pharazôn's possible redemption might involve playing a role in "the restoration of Numenor, part of the 'highway' that will come out of the depths, as the wave that covers it is rolled back." This idea of a highway from the deep comes from one of the revelations of Joseph Smith. Here is the immediate context:

And they who are in the north countries shall come in remembrance before the Lord; and their prophets shall hear his voice, and shall no longer stay themselves; and they shall smite the rocks, and the ice shall flow down at their presence. And an highway shall be cast up in the midst of the great deep (D&C 133:26-27).

William didn't quote the part about the ice flowing, even though it seems relevant to his frozen-Númenor theory, but I found it just by searching for sci-fi novels with Europa in the title.
