The Book

Suddenly, the book appears in your hands and the invisible barrier disappears. You are able to walk through the doorway, but as you start to, the book falls out of your hands and lands on the ground, open to a random page. Suddenly, a swirling portal appears over the book. You look back, but your dad isn't there. You have a string feeling that, to figure out what is going on, you need to jump into the portal.
