Raven Koynes is a woman in hiding. Years ago she escaped to remote Gull Island Light Station, nestled far away in Lake Superior. She has carved out a life of peace and solitude for herself. Until famed nature photographer Sebastian Knight arrives—in the height of a nor'easter storm—to document the beauty of Gull Island. Unsavory treasure hunters also blow in with the storm, determined to find missing cargo from a sunken ship. And they think Raven knows where it's stashed. A power outage is a final threat, pushing Raven to the limit.Help arrives in the form of a stray German Shepherd Dog, who takes an immediate protective interest in Raven. He becomes her constant shadow and listening ear as she sorts out her growing—and conflicting—feelings for Sebastian.Meanwhile, Sebastian came to the island looking for treasure as well, in the form of photographs, While he isn't so sure about a sunken boat and missing cargo, he only needs one look at Raven Koynes to know he's found his own valuable treasure. One he hopes he can hang on to once she learns about his mysterious secret.Now that Madeline the resident ghost has found out, it's probably just a matter of time until Raven does too. And with the storm and power outage, no one is going anywhere any time soon.
