Plasmanomicon

Jenny's human date giving her a copy of the book.

The Plasmanomicon was a book of eldritch lore, written by “a mad Arab, or something”. Only three copies of it existed in its universe, where a young man sold his soul to a Hellhound in exchange for one of the copies, which he intended to gift to Jenny Everywhere as a Valentine's Day present.
