In some ways, this is an incredible book about growing old with the one you love.

Then things get weird.

I was particularly pleased with the description of two senior citizens struggling against an ocean enraged by both a hurricane and the presence of a nascent elder god.

There are relatively few books in which the elderly function as protagonists, and Schlossberg not only makes you care for the pair of them, but also makes their plight and actions in the face of a personal apocalypse feel perfectly appropriate and natural.
