Run to You by Jayne Townsley

A friend of the family has done despicable things and has his eyes set on Rin and she has no idea what he has in store for her.
Rin lost her mother four years after the murder of her best friend on the night of their high school graduation. Although her mother’s death was unexpected, there is nothing suspicious about it whereas Hannah’s death is an open cold case. At least Rin thinks her mother’s death was nothing more than an untimely tragedy. Going on the long dreamed of post-college vacation that she and her friends have been planning since grade school, she hopes to leave the pain behind for a bit and relax in the Florida sunshine.
Kevin loves his life and his job as an Army Ranger. When he and his Army brothers use some well-earned time off to visit Panama City Beach, he’s not expecting to meet the woman who will change his life forever. A woman being hunted by an unknown monster intent on keeping them apart by any means necessary.
Can Kevin keep Rin from Hannah’s fate? Or is it his turn to face loss like Rin?
