T.A. Miles is a being owned by curiosity and fueled by internal magic. She claims to have fallen down a rabbit hole as a child, but in reality seems to be living in a semi-permanent out-of-body experience where she meets fantastical people and magical creatures in lands unknown to earth. She believes her characters are real people, and she publishes for one reason only: to share these people and the experiences they relay in carefully constructed stories unmarred by common human perception. Which sounds very complicated. It's easier to say she prefers to write about exceptionally human experiences.
Let's not try to explain that, actually. It's simpler to read one of her books instead. Remember to read with your head and your soul.
