Magic apprentice who can see magic and princess work together.

A magic apprentice who can see magic and a princess work together in this book. All actual magicians have tattoos on them as a sort of right of passage. The POV switch’s between the princess and the apprentice magician. It’s a book series. I think the princess has a dragon too but not 100% sure on that. In the second book I think the apprentice gets his first tattoo right under his eye.
