In Ember, Pennsylvania there is a place known as The Hollow. A spot believed to only exist on October 31st.
Teenage best friends, Paige and Jojo, have always dreamed of finding the doorway into The Hollow, and discovering what awaits beyond. On the morning of Halloween 1998 they go looking for what they believe to be their ticket to making their dreams come true. But what they find leaves them with a choice they never expected to have to make.
