The Stroke of Winter By Wendy Webb

In the tourist town of Wharton, on the coast of Lake Superior, Tess Bell is renovating her old family home into a bed-and-breakfast during the icy dead of winter…

As the house’s restoration commences, a shuttered art studio is revealed. Inside are paintings Tess’s late grandfather, beloved and celebrated artist Sebastian Bell, hid away for generations. But these appear to be the works of a twisted mind, almost unrecognizable as paintings she and others familiar with his art would expect. The sinister canvases raise disturbing questions for Tess, sparking nightmares and igniting in her an obsession to unearth the truth around their origins.

What evil has been locked away for so many years? The ominous brushstrokes, scratching at the door, and moving shadows begin to pull Tess further and further into the darkness.
