What is the author's style in A Visit to William Blake's Inn by Nancy Willard?

The style can be found in the language of the poetry. Since Willard is very good at writing seamless verse with impeccable scansion and syllabification, and because this is a children's book, at first it may be possible to miss the elegant and mature use of language in this book. Dealing with spiritual themes, sometimes the verses have a scriptural cadence, such as "and many are the stars he's named/ and many those who stop and take/their joyful rest with William Blake."
