I've read the teachings of the christian mystics as well as Son of Man: the mystical path to christ by andrew harvey. The teachings of th emystics is not his writing, rather it is a compilation of various writings form a number oof christian mystics, like Jesus himself, st Paul, Gregory of nyssa Hildegard of Bingen Meister Ekhart and many more. I do appreciate his writing style, and the thing that I like most about him is his love and devotion to the divine mother. I've had a few profound experiences with her myself, and really connected to that aspect of his writing.
