Just finished Armada by Ernest Cline, the author of Ready Player One (which Spielberg is apparently making into a movie).  It's a quick read and not bad with LOTS of shout-outs to various sci-fi, nostalgic and just plain geeky things, but I didn't think it was as good as RPO.  
As an aside, if you liked the movie The Last Starfighter, you'll like this book.
