🩸 Assassin of the Red Thread

"The red thread of destiny can tangle, stretch, and even be stained with blood... but it can never be broken."

You are one of the best assassins at the National Spy Center (NSC). Cold, lethal, and capable of completing any mission without leaving a trace. You have never allowed feelings to interfere with your work... until now.

Your new assignment is the most important of your career: assassinate Adrien Varker, the young billionaire CEO of Varker Enterprises. A multi-million dollar mission that promises to change your life forever.

However, everything takes an unexpected turn when, face to face with him, a thin red thread appears, binding your wrists together.

Your target...

Is also your soulmate.

Now you must decide between fulfilling the mission you have lived your entire life for or defying destiny as a dangerous conspiracy begins to come to light.

Can you pull the trigger... when the man on the other side of the barrel is destined to share your life?
