Sol Angelica var blitt tyve og skulle reise ut i den store verden. Enderlig var hun fri - fri til å lete etter heksene ved Brösarps Backar, fri til å dyrke mørkets fyrste, fri til å gjøre alt hun så lenge hadde drømt om. Men Sol var ikke bare opptatt av den onde. For sine nærmeste ville hun gå gjennom ild og vann, til og med ofre sitt eget liv. 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…
