Darker than Dark — Alexie Aaron

Gwen hates the dark. Most children do, but she has more reasons than most. At night when the lights go out, entities that are darker than dark crawl out of the woodwork and torment her. A call to mommy brings relief as the lights go on, and the darker than darks scurry away. But not tonight. A thunderstorm leaves her family without electricity, without light, vulnerable to those who thrive on darkness.

Meanwhile, Murphy is noticing that spirits of the Iroquois and Fox tribes from the 1650s are massing in the north woods of his land. Why are they there? What do they have to do with Gwen's tormenters? All will be answered as Mia and the PEEPs team, with the help of Angelo Michaels ("Ghostly Attachments"), investigate this haunting and shine light on what is truly darker than dark.

This is book four of the "Haunted Series."
