Rise from Ruin by JL Madore

The three have become the five.

As crazy as it sounds, I’m bound to three sexy, bioengineered super soldiers. In a moment of battle, with blood flying and passions heightened, Link, Shift, and Flash were not only freed from their stasis, their powers engaged. I am their catalyst.
I don’t know what to think about that… Connor doesn’t either.
With Shift imprinted on him and the three of them bound and bonded with me, it’s a big mess. As the pull between the five of us grows stronger, Andras Brass and his army come at us, determined that the three never reach their full potential.
