Hmm, I get the references in shadow hunter, district 12, divergent, and probably the selection… is the assassin a reference to Throne of Glass? I'm not sure about the runaway thief, although it brings to mind The Runaway King. What books were you thinking of?
And would you mind looking at my book The Royal Thief or Elementals (whichever you want, one is a sort-of Avatar fan fiction, but The Royal Thief is completely original) if you have time?
