The missing season
(Book)

After moving to a new town for her father's job, Clara learns that kids go missing from Pender every October and that a monster named the Mumbler may be responsible.

Every October another kid goes missing from the old factory town of Pender. There's a monster out in the marshes, called the Mumbler. That's what Bree, Sage, Trace and Kincaid tell Clara when she moves to town with her father. Clara doesn't actually believe in the Mumbler, not like Kinkaid does. But as Halloween gets closer and tensions build in the town, it's hard to shake the feeling that there really is something dark and dangerous in Pender. Lurking in the shadows. Waiting to bring the stories to life. -- adapted from jacket
