I just finished Finity's End By C.J. Cherryh.

Finity's End is part of a series of books by Cherryh set in the same universe.  I've posted about a few of them (Rim Runners, Heavy Time and Hellburner).  This one is less claustrophobic than those books, almost a YA book, since it deals with the classic disaffected youth gaining maturity and a place in the world as he overcomes problems.  In this case, it is the child of a spacer who was left behind on a station during an emergency.  Since then, he has been the subject of legal struggles between the station and the spacers, and grew up to resent everyone.  When he is sent back to the spacers, he has to grow up and make a place for himself.

As cliched as the basic story is, it still works and makes an effective story.
