Twelve-year-old Tee didn't think she believed in ghosts . . . until a walk in the woods around her new rural Alaskan home changes her mind. She and her beagle, Henry, are stalked by a wolfish, decidedly spooky shadow. There's something out there - and it's not of this world. With Henry and new friend Quin in tow, Tee is determined to capture evidence of the ghost and unravel the mystery of its origins. But with every sighting, the ghostly presence of the Shadow seems to gain strength. This ghost dog may pose a real live threat - that is, unless Tee can stop it.
