Just an avid reader. Mostly SF/Fantasy, some hobbies, paranormal, urban fantasy and lighter, fluffier things.
The comparison likely will just do them a disservice. In my opinion, few are going to measure up and will just be disappointing --plus, major reason for the popularity of books like Graceling - Kristin Cashore and Seraphina - Rachel Hartman is that they aren't comparable to other books out there.
Just reading the description, it actually sounds like would be more comparable to The Queen of the Tearling - Erika Johansen or Falling Kingdoms - Morgan Rhodes anyway (if only because the main character is disenfranchised royalty versus "lower caste").
