I recently finished reading Anomaly.
Although quite short, and more like a long short story, this had some great concepts and is well worth the read. Not your typical alien first contact storyline, I found this engrossing and somehow plausible. Oh, except for the bit where the U.N. invades the U.S., that was jsut silly, but nevermind.
OK, I don't want to spoil any of the actual interesting content, so just go read it. Short, cheap, interesting.
