Deep in the forest outside Sobolton, there's a pit that no-one dares approach. A creature is said to dwell there, waiting in the dark for its next victim. Some say it's only a story. Others whisper that the creature died long ago. They're all wrong.

When a young girl is found dead, Sheriff John Tench is pulled into a mystery that runs deeper than he ever imagined. The trail leads him to the edge of town - and into one of Sobolton's oldest and darkest legends. What he finds there could destroy everything he thought he knew about his community, and about himself.

Meanwhile, Lisa begins to experience strange inconsistencies in her daily life - subtle, creeping signs that reality might not be what it seems. As buried memories surface and a hidden enemy draws closer, she realizes the past isn't done with her yet.

In a Lonely Grave is the fourth book in the Horrors of Sobolton series, which tells the story of one small town's struggle to deal with the paranormal monstrosities on its doorstep. Each book tells a standalone story, but there are cliffhangers and readers are recommended to go through the series in order.
