' ' Perfect Enough To Break ' '

Once, they were weapons. Now, they're something far more dangerous.
Trained by HYDRA. Sharpened into silence. Together, they were nearly unstoppable-until their paths split in blood and secrecy.
Years later, he's with SHIELD, with the Avengers, fighting for the side he once destroyed. She's still in the shadows, loyal to the system that built her.
When a mission forces their worlds to collide, old instincts kick in-and so do feelings neither of them should still carry.
Enemies on paper. Something else entirely beneath the surface.
But the past doesn't let go, and neither does HYDRA.
And in the space between duty and desire, someone always bleeds.
