The author is a delightful person and her talent/ability unmistakable. This story is clearly presented if perhaps a touch simple.

It's certainly not the author's fault that I left off Anne McCaffrey's 'Dragonsinger' to enjoy 'The Miserable Prince'; most fantasy tales would suffer by comparison! But the two stories have their similarities; in each case a lighter, less earth-shaking plot than the standard Tolkein or Lawhead or Rowling fare, both relying on character strength perhaps than gripping narrative.
If 'The Miserable Prince' stumbles slightly, in my opinion it is because the author does not give me enough time on any one character's shoulder. The POV changes were rarely confusing, but while in 'Dragonsinger' McCaffrey lets Menolly carry the entire tale, and one is invited to experience her pain and grow to love her, the ball was passed between so many in 'Miserable Prince' that it was all I could do to keep up; and, again, no Tolkein-esque narrative to pull me along.
But though it could be stronger, it is a lovely story just the same
