Published: February 13, 2014.
Lily Harper narrowly survived her first mission as a Soul Retriever in the first level of the Underground City. After that harrowing trip, she wants nothing more than some down-time, but as with most things involving the afterlife, nothing ever quite works out the way Lily wants it to.
Her newest mission will see her traveling to the sewer aqueduct of the Underground City and later, the prison.
