Book

Book is a major character in the Thirteen-Tulpaverse. She is very intelligent and sometimes brags a bit. She and The Grout rule the Cum Zone together.

Book's parents were killed in a car accident by Taco in August of 2014, leaving her both an orphan and homeless.

A day later, The Grout saw her begging for food and shelter, so he decided to take her under his wing, as she knew how it felt to be abandoned. The first thing he told her was that her cover was beautiful.

Later on, she and the Grout started to date. They were destined to be together, and if one of them died, the whole world would fall apart.

Book is seemingly nice and caring towards most characters. However, she known to be arrogant occasionally, such as claiming that she will win Dream Island.

One day, 13 decided to give her a potion that would make her a hellspawn hybrid, so she'd have the same amount of power as the Grout. From that day on she was a hellspawn-dictionary hybrid.

Whenever Book is very angry or extremely happy, she will grow into her giant form, which is a side effect of becoming a hellspawn. She enjoys being a giant, and the Grout loves her that way too. She can also shapeshift.
