Variable Star
I've just finished reading Variable Star today - around 2 AM - I just couldn't stop reading... It is a book by Spider Robinson based on the a recently found outline for a juvenile by Robert A. Heinlein. It is a very good read. The tidbits on the end about how he wrote it in Heinlein's cufflinks and how the first book he ever read was written by Heinlein are quite interesting,too. The ending did feel a bit Deus-Ex machina, though. That said, I'd love to see a sequel! Looking around I found a interview with the author, who said he haven't thought about it. That is a bit hard to believe, given how the sequel was left nicely open AND sounding interesting.
