I'm not generally a huge fan of historical fiction, unless it's written by Rosemary Sutcliff, Dorothy Dunnett, Hilary Mantel or Antonia Forest, so I'm not sure about the Cornwell. Though Divergent sounds like it might be a bit too formula-YA...

Of course, I don't actually have to use the credit at all. It's not as though I'm short of books on my kindle.
