Existence Trilogy

In the Existence Trilogy, Abbi Glines writes fiction stories evolving around Pagan Moore. The three book Existence, Predestined and Ceaseless tells the story of Pagan Moore and her tribulations as she falls in love with death. The other book, Leif, talks about another character in the series called Leif. Abbi finds the need to tell the readers more about Leif Montgomery who is a soulless high school quarterback who disappears. The author finds it necessary to expound on the character Leif because he represents a different kind of soul.
