Mercury Books in Order

The Mercury books take apocalypse fiction and treat it like a cosmic workplace comedy with very real stakes. At the center is Mercury, an angel whose official job is to help prepare the End Times. He is not especially good at following orders. He would much rather enjoy earthly distractions than carry out some vast heavenly plan, which makes him a terrible bureaucrat and a very useful hero.

In Mercury Falls, he crashes into the life of Christine Temetri, a religion reporter who has spent years covering failed doomsday cults and has just about run out of patience. Christine becomes the human anchor of the series. She is skeptical, practical, and usually the first person in the room to notice that both Heaven and Hell are being run by people, or beings, with terrible judgment. Later books widen the cast with allies like Jacob Slater, while also bringing in Antichrists, demons, fringe reporters, billionaires, and rival heavenly factions.

Heaven, in these books, is never as tidy as it sounds.

What makes the series work is the collision between the ordinary world and the machinery behind prophecy. Kroese treats angels, devils, and end-of-the-world plots not as distant symbols but as participants in petty arguments, bad decisions, and sprawling conspiracies. The books move from modern cults and looming disaster to ancient Troy, Mesopotamia, hidden cabals, time travel, and alternate realities, but the voice stays light on its feet. Even when the universe is in danger, the stories never lose their sense of comic timing.

Under the jokes, there is a real ongoing tension about fate and free will. Mercury keeps bumping against plans that are supposed to be inevitable, and he keeps refusing to act like inevitability is a good enough answer. That gives the whole series its shape. If you like fantasy that mixes theology, satire, action, and a few very bad celestial management decisions, Mercury is a good place to settle in.
