The Star Kings, by Edmond Hamilton

This rip-roaring space opera. It's Buck Rogers stuff. Boring desk-job John Gordon swaps minds with Zarth Arn from the year 202,115. In the 200th millennium Gordon-as-Zarth Arn finds himself a prince of the Mid-Galactic Empire. He wins the heart of a princess, fights a galactic war against the evil League of Dark Worlds, and looses the awful power of the Disrupter—a weapon with the power to rip apart the very fabric of the galaxy itself!

It's not high-brow literature, and it's very much space opera, pulp-era proto-science fiction. That's fine, and it's a satisfactory story. I'm not sure I'll seek out a sequel though. This kind of story is enjoyable, but it needs a special quality of writing, something that (at his best) Edgar Rice Burroughs could provide but which is lacking here. The Star Kings goes through all the motions and hits all the proper plot points, but that's what it feels like: that it's going through the motions and hitting the proper plot points. It doesn't move my soul like ERB's John Carter stories.
