Dark Hollow by Brian Keene

Something very strange is happening in LeHorn's Hollow...
Eerie, piping music is heard late at night, and mysterious fires have been spotted deep in the woods. Women are vanishing without a trace overnight, leaving behind husbands and families.

When up-and-coming novelist Adam Senft stumbles upon an unearthly scene, it plunges him and the entire town into an ancient nightmare. Folks say the woods in LeHorn's Hollow are haunted, but what waits there is far worse than any ghost. It has been summoned...and now it demands to be satisfied.
