Reddit mentions of Shade's Children

I think these are all a few years old, but I've enjoyed all of them:

• Jumper by Steven Gould is brilliant, although if you've already seen the movie then I suggest Wildside instead, which is very nearly as good. Can also recommend Blind Waves, set around a floating city, after the icecaps have melted.
  
  
• Garth Nix's Abhorsen trilogy is brilliant fantasy - if you prefer sci-fi, I recommend Shades Children.
  
  I'm sure that, when I started composing this comment, there was someone else I intended to recommend, but I'm afraid I'm a little tired right now, and I can't remember who it was.
