You're PewDiePie's sister and you meet his friends when you go with him to revelmode. After a little bit, you start to develop feelings for Sean, or Jacksepticeye.
A story about a baby (you) and Markiplier.
Not a very big description, but the book speaks for itself.
Disclaimer: I don't own Markiplier, or any of the artwork.
Hope you enjoy! :)
