As the site of a former military base, there have always been rumors that East Township High School was the site of experiments with space and time. For years, students have whispered in the hallways of a doorway created within the school, one that can access multiple timelines and realities, a place known as the Down World.

As the new kid in school and still reeling from the unexplained death of her brother Robbie, Marina O'Connell is only interested in one thing: leaving the past behind. But a chance encounter with handsome Brady Picelli changes everything. He will lead Marina to a startling discovery. The Down World is real and the past, present, and future are falling out of balance.

Brady is determined to help Marina discover what really happened to her brother. However, what is taken from one world, must be repaid by another. And Marina is about to discover that even a realm of infinite possibilities has rules that must be obeyed.
