About This Book
The salty sea air fills Briana's lungs as she steps onto the cold shores of Norway, her heart pounding with fear and hope. Every creak of the wooden ships and whisper of the wind reminds her of home and the brother she longs to see. In a land of Vikings and strangers, Briana clings to her prayers, waiting for a miracle that could change everything.
