The Pleiadian Workbook: Awakening Your Divine Ka and The Pleiadian Tantric Workbook: Awakening Your Divine Ba are a wonderful set of books by Amorah Quan Yin.
These two books are channeled teachings from the Pleiadians, a family of light beings that have regularly communicated through several different humans in order to share their divine wisdom. 
The Divine Ka workbook will help you embrace your true nature by awakening the life force within, to help transform you into a more peaceful, heart-centered, spiritually aware individual.
While the Divine Ba workbook focuses on sacred spiritual relationships, healing the soul and sexual energy.
