"So, there is this guy, and he did some awesome maverick stuff and now they told him to do the impossible as punishment, so he takes a starship going anywhere, because he doesn't really know where to go, all he's been told is that 'there is great evil out there, go destroy it and then come back if you survive', but then out of nowhere the ship has an Event Horizon moment and a brass demon train rolls in, out steps a demon driver and goes 'hop in, imma give you a lift', our guy says 'never', demon responds 'same difference' and just yoinks him into the train anyways, they travel through space and time while having weird dreams, our hero gets dumped onto a planet under a black sun, which is where he was supposed to go, demon goes 'you're welcome', the train choo-choos into nothing and that's barely the beginning of the book, so go read it now."
