What happens when a girl walks in on an assassin about to execute someone?

On a frigid winter night, Ember Oleander, a botanist by day and chocolate hoarder by night, accidentally stumbles into a dark alley. Her quiet, simple life is forever changed as she comes face to face with a dangerous stranger in odd-looking attire executing someone with a wicked-looking dagger.

The mysterious man takes an interest in her. Raised and trained in an organization of assassins, this man is their crown jewel. He is known for his lethal focus, killer instincts, mastery of weaponry, and, most of all, his haunting silence.

They should never have met. They have nothing in common. This newfound connection can end their lives.

There's no going back.
