There’s one Ender book left (Ender in Exile) but I don’t have it yet. I see it’s available on the Kindle. I’ve been focusing on the Shadow saga for the last week or so. I’ve been very surprised by the Shadow books – I think I’ve enjoyed all them more than the Ender saga books. My favorite Orson Scott Card book so far is either Shadow of the Hegemon or Ender’s Shadow. I just finished Shadow Puppets and moved on to Shadow of the Giant.
I’m also still reading The Art of Learning: A Journey in the Pursuit of Excellence by Josh Waitzkin. It took me about a 100 pages to get into it, but I’ve been really enjoying it since then.
