A NEW BOOK ON MARY MAGDALENE by Betty Conrad Adam is reviewed in the Houston Chronicle (free registration required). It is devotional rather than scholarly:

What makes Adam's book different from others is its conversational tone, roundup of past research and legends, and a focus on adapting Mary Magdalene's spirituality for today's world.

"It helps us envision our spirituality in new ways," she said. "It's a message that I believe inspires a new way of thinking about ourselves and others. I talk about it in terms of the contemporary community here."

Adam and others refer to the Gospel of Mary, as the "gospel of peace" and look to Magdalene's teachings as a way to bridge barriers in today's world.

Mary Magdalene's teachings are pretty thin on the ground, but perhaps she is referring to the Greek and Coptic Gospel of Mary, which is mentioned in the article as well. Like the Gospel of Judas, this gospel is much later than the canonical ones and tells us interesting things about the second century church, but nothing new about the time of Jesus.
