The Magdalene Line is a series of novels, featuring both fictitious and historical female characters which the author believes history has either misrepresented or obliterated.

Kathleen McGowan began working on the first novel The Expected One in 1989. Focusing on the role of Mary Magdalene, it was self-published in 2005, and sold 2,500 copies. On July 25, 2006, the book was re-published by Simon & Schuster under the Touchstone imprint.

The second novel of the series is The Book of Love, published in 2009, focusing on the life of Saint Mathilda of Canossa.

Each novel of the series features the fictitious heroine Maureen Paschal, who is tasked with uncovering alleged historical and Christian enigmas. Other fictitious characters include Berenger Sinclair and Tamara Wisdom, as well as the enigmatic character Destino.

The Source of Miracles is a self-help book, based on the Lord's Prayers and offering the reader seven steps to transform their life. The process is based on the six-petalled rose depicted at the center of the Chartres cathedral labyrinth.
