Count Crowley: Mediocre Midnight Monster Hunter #4 Book by David Dastmalchian

The vengeful spirit of a Halloween tragedy terrorizes the children of Beloit but before Jerri can learn how to bust this ghost, she'll have to face off with a vampire more powerful than anything she's faced. As the stakes increase, all nefarious roads seem to lead to Kansas City, where a provocative lab of re-animated corpses have been used for some unsavory business. The body count rises, the spirits are conjured and something unspeakable will befall one of Jerri's most important allies.
