Alberte 'Abby' Valdemar is a quiet, curious Christian teenager who loves to read. The new school year drops something interesting in her path, a new girl in her class, Lilith Magnus, a coy soul with wide eyes, a fun spirit and a different outlook on life, the kind of person to get Abby's inquisitive wheels rolling, who preys on her curiosity and plunges her family into a world of danger, spiritual warfare and uncertainty.
