Last Breath - Robbi Sommers Bryant

She thought the nightmare was over. He wants her dead. 

Nurse Caitlyn Derry believes she has stopped a monster. When Edward Olson-the man suspected of a string of brutal murders-lies helpless in her ICU bed, Caitlyn makes a choice she will never be able to undo. One quiet moment. One syringe. One chance to end the killing. 

But Edward survives and knows exactly who tried to kill him. Now he watches, learns, and plans. Patiently waiting for the perfect moment to strike.

As Caitlyn and Edward play cat and mouse around the rural towns of Northern California, The Darkness-an evil neither can control-never breathes a last breath.
