In The Depths of Darkness, Sol Angelica, the beautiful and restless niece of Tengel, becomes the focus of the story…At twenty years of age she is able to give full and free rein to her long-held wish to seek out ancient witches covens in the lowlands and to worship the Powers of Darkness unrestrainedly. At last she feels ready to fulfil all her secret and depraved dreams of power and carnal passion.

Yet like her uncle Tengel, all her impulses are not evil – it is not only the dark powers that guide her. And she finds she is ready to give her life to protect those nearest and dearest to her…
