Spirits in the Trees — Morgan Hannah MacDonald

EVIL DOES EXIST
An abandoned house, a serial killer, and a victim reaching out from the grave. A woman races against time to unearth deeply buried secrets before she becomes a ghost herself.
YOU ARE NOT ALONE
Madeline Anderson goes to Isabelle Island, Washington, to sell a family home abandoned over forty years before. Strange things occur the moment she arrives, items move about on their own accord. Noises come from empty rooms. She has a recurring dream of a woman running for her life. But most disturbing is that the wind rustling through the trees sounds like urgent cries. When the cacophony dies down, one single word emerges: Madeline, Madeline, Madeline.
YOU CAN'T HIDE
The man helping her with the renovations, Doug Lindstrom, is certain she's jumping at shadows because the local kids said it was a haunted house. That is until he witnesses horrifying events that even he can't explain. After Maddy's life is threatened not once, but twice, Doug vows there won't be a third. He'd rather die saving Maddy than live without her.
THEY SEE ALL
While searching for answers, Maddy uncovers dark family secrets that only lead to more questions. She digs deeper until she stumbles across evidence of an old cold case involving a serial killer named The Seaside Strangler.
Now Maddy must unmask a killer. The life she saves just might be her own.
