Length Issue And Possible Name Change for "Cardiac Arrest"

Due to length issues and word count restrictions, I'm exploring the possibility of rolling over the final chapters of my sci-fi/fantasy novel, "Cardiac Arrest", into its sequel, "The Mask of Beelzebub".  As a result of these pending changes, the name of the novel could change.  One of the main locations in the novel is a place called "Cadaver Island", which could become the new title of the first book.
