I am looking for a novel that I'd love to re-read it with my wife (my 13-year old self must be proud of me I guess).
Key Plot points
The plot was about humanity finding an alien station on an orbit of Earth. (I'm not sure if it wasn't Moon itself).
On this station there were thousands of ships ready to travel so there rose a company that paid people to get on those ships and explore the galaxy.
The problem was humans didn't understand how to steer those ships so they had to rely on preset targets. Of course there was no telling where particular ship was to go and fair amount of them never returned.
Chronology and other relevant information
I read it as an early teenager back in early 2000s. It was Polish translation of a foreign (possibly English) story.
I think (not sure) that the book wasn't new at the time. It was just one of those books you dig out in a library and take to see if it's good. I don't recall cover either and even if I did it'd be of the Polish version.
Additional information could be that the narration was led along the psychoanalytics of the main protagonists where he relives his memories from inside the station and his journeys.
