Red Thorn : Glasgow Kiss

Although she grew up in America, gifted artist Isla Mackintosh is a Scot at heart. Both of her parents were born in Glasgow, and 25 years ago her older sister Lauren vanished during a visit to the land of her ancestry. Now, Isla is following in her sister's footsteps, hoping to discover the truth behind her disappearance. The secret she's about to unearth, however, is far older and more dangerous than she ever could have guessed. Something has been waiting for Isla, deep beneath the moors. A pagan demigod has been trapped there for millennia, caged inside the bones of ancient gods. He smells of the blood of a thousand enemies and the sweat of countless lovers. His name is Thorn, and Isla's art is the key to his freedom.
