With the Dark Avenger no longer a threat, life has returned to normal for everyone but Mitch Hamilton. He just can't seem to shake the young, unknown blonde who's made herself an annoying presence in his life. With the Halloween Carnival right around the corner, Mitch is already under enough strain, and he turns to Brenna for help. Along with Van's assistance, the couple fabricates a romantic relationship designed to draw out the stalker. But as the lines between fake and real romance become blurry, it is Brenna who becomes the focus of Mitch's Mystery Girl. As strange occurrences pile up, Van is convinced that they might not be dealing with a flesh and blood girl after all and that the real danger may be much closer than they think.
