In Moonbound, Robin Sloan has written a novel with the full scope and ambitious imagination of the very books that lit the engines of Mr. Penumbra's 24-Hour Bookstore: an epic quest as only Sloan could conceive it, mixing science fiction, fantasy, good old-fashioned literary storytelling, and unrivaled enthusiasm for what's next.

It is eleven thousand years from now . . . A lot has happened, and yet a lot is still very familiar. Ariel is a boy in a small town under a wizard's rule. Like many adventurers before him, Ariel is called to explore a world full of unimaginable glories and challenges: unknown enemies, a mission to save the world, a girl. Here, as they say, be dragons. But none of this happens before Ariel comes across an artifact from an earlier civilization, a sentient, record-keeping artificial intelligence that carries with it the perspective of the whole of human history--and becomes both Ariel's greatest ally and the narrator of our story.

Moonbound is an adventure into the richest depths of Story itself. It is a deeply satisfying epic of ancient scale, blasted through the imaginative prism one of our most forward-thinking writers. And this is only the beginning.
