They call it a boost. It’s the buzz you get from absorbing the spiritual-energy of the dead, and it absolutely terrifies Lidia Powell. Shortly after meeting Ander at summer camp, Lidia is thrust into the world of psychic mediums and brought to a new school.
At Mountain Heights Academy, even a casual pizza date is accompanied by a ghost, and only a frightened uberdork would refuse the boost. To Lidia, the peer pressure to absorb phantom apparitions is horrifying, but to everyone else, it's the drug of choice. However, when one of the students delves into dark energy, Lidia suspects that a boost isn’t as innocent as it seems. Soon, the boost becomes an addiction and Lidia must act fast before the changes become irreversible.
