The book "A Glimpse into the Unknown: A Journey into a Portal; Catching Sight of the Other Dimension: Discovering the Undiscoverable: A Curiosity Piqued and Peaked." was authored by Abby and Erin in the 2016 movie. Note that this article is developed being based on the deleted scene "The New Book", as in the film it is only briefly seen when Erin opens a box of them, in Abby's hands as she is walking, and placed on a lab table in Jillian's area of the ground floor.
