After surviving a harrowing case, Alex McKenna just wanted to rest. Unfortunately, his plans are interrupted by the ghost of Seven-year-old Haven, who is lost in an in-between realm.

Despite his great-grandmother's warning, Alex crosses the bridge between the living and the dead, sending him and his girlfriend into the world of the Academy of Souls, a high school for dead teens who are unable to complete their journey.

There, Alex meets Ophelia, Haven's teenage sister, who's been searching for her for more than a century. Together, with a few friends he meets along the way, Alex must cross the treacherous terrain of the Underworld in-between, to save Haven from the clutches of the Soul Gatherer and reunite the sisters.

For Alex McKenna, high school is just a distraction from the love of his life, Margaret, with whom he can't wait to spend more time once they get to college.In many respects, Alex is just an average seventeen-year-old boy...except for the fact he's a transgender medium born from a long line of Strega witches, possessing the ability to communicate with ghosts.

With the help of Margaret and his talented Strega great-grandmother, Alex will learn how to strengthen his abilities. The dead need Alex to help them reconcile issues they left behind—and he finds that he needs them, too.

As his abilities multiply, assisting the dead becomes an outlet to channel his new energy, giving him the strength to come to terms with who he is as a transgender male, and how far he will choose to go.

High school is difficult enough, but when you're dead, it comes with an entirely different set of problems.

Ophelia is a fifteen-year-old spirit who found sanctuary in The Academy of Souls, a school for teen souls who haven't found their way to the next life. When the spirit of her younger sister, Haven, is kidnapped, Ophelia refuses to move on without her.

But searching for Haven isn't the only issue Ophelia is forced to face. Her soul still has a link to her former body, creating even more obstacles. To add to her already confusing afterlife, she finds herself mesmerized by a new student, a seventeen-year-old boy who is very much alive.
