New here, I was hoping to track down a book I failed to finish as a kid. I think I probably read it between 1999 and 2007 or so, so it's at least that old.
The protagonist was some sort of street kid, potentially wasn't always but my the beginning of the story he is. He finds himself on the run, and has to cut out his wrist implant with a blade. It's sort of a dystopian future where everyone has an implant which keeps track of money and tracks them.
I remember two specific settings from the story, one being a space station that he goes up to. It was close by, so probably Mars or the Moon. The other I remember a little better, he ends up fleeing into this underground "old New York", which I think even talked about the Brooklyn Bridge, but everything in darkness, and he could hear and sense other people or creatures down there, including something big.
Sorry if that is a bit vague, any help would be great!
