This question already has an answer here:
I read this book about 1988-89.
Sci fi, dealt with an alien space station (out in deep space) that humans stumble upon, long abandoned by a possibly insect-like race, human sized (they can tell from the shape of the chairs and such) and the station is full of ships. If you get in one and press a button it will go on an indeterminable round trip to another star. It could be a day, could be months and months. People get paid 'rewards' for taking out a ship and if they return with valuable destinations (another station or something of interest) they are paid quite well. It's written from the perspective of one of these would-be 'gold rush' guys who wants to try his hand... he ends up almost landing in a black hole or something like that.
Any help identifying this book? Author/title etc? I would love to read it again :)
Thanks a bunch!!
