I read a previous book by this author and was delighted to find out this one was xenofiction.

An alien race finds out that a human, Andrew Martin, has solved the Riemann Hypothesis and that just would not do. They sent someone out to ensure this information didn’t spread through humanity, and that someone is the narrator of the story.

The alien takes the form of Andrew and attempts to adjust to being human while trying to delete all evidence of the solved hypothesis. This alien was to murder anyone with whom Andrew shared the knowledge.

At first disgusted by humans, AlienAndrew grows to enjoy the company of the son, Gulliver, and the wife, Isobel and chooses to keep them alive rather than kill them. This, obviously, causes problems.

The author manages to highlight a lot of the dichotomies of being human and does so in a manner that never let me forget that the main character is an alien. There’s a lightness in the narration of heavy concepts, which I found delightful.

The book is remarkably moving, well written, and a curious glance into what it means to be human. Definitely would recommend to anyone.
