London calling Neptune: Mansfield, Keith. Johnny Mackintosh. London: Quercus, 2008.

Fun, but too many ideas. Johnny lives in a children's home. He's fantastic with computers. He gets kidnapped, discovers a sister, is taken off by aliens, given a space ship, sent ack to Atlantis, discovers his mother is something terribly important and is quite obviously going to tun out to be a relative of the Emperor of the galaxy (who looks suspiciously human).

On the other hand the London setting is lovely, the space ships living beings, and some interesting stuff about aliens.
