What is the author's style in On Location in the Loire Valley by Diane Ackerman?

The poem is written in the form of a ghazal. This poetic form has strict requirements, although Ackerman chose not to observe all of them. A traditional ghazal is a poem of five to fifteen couplets. Each couplet should be a self-contained poem that does not depend on the others for its meaning, although it is permissible to have all the couplets carry the same or similar theme. Because each couplet is self-contained, there should be no run-on lines, or enjambment, between couplets. The length of the lines must be the same. The second lines of each couplet must all end with the same word or words. This is the refrain. There must also be a rhyming pattern to the words that immediately precede the refrain.
