Cross-Over Element in "Cardiac Arrest"

The final chapters of my fantasy/sci-fi novel, "Cardiac Arrest", will feature a crossover element from my short story, "Citadel of the New Moon", which was published in Fantasy and Fear 3 from Pro Se Press in January 2011.  An important component of "Citadel" will affect the outcome of the novel's climax.  The crossover element will create a bridge to the second novel in the trilogy, which will be called "The Mask of Beelzebub".
