Marked by Sin

A Dark Reverse Harem Demon Academy Romance (The Infernal Mark Book 1)

Power always demands a price.
Mine came in the form of three deadly men.

The academy was built to train monsters.

Killers with perfect smiles. Beautiful liars who can end your life without blinking.

I was never supposed to be here.

But the power inside me won’t stay hidden—and now the most dangerous men in the academy are watching me like I belong to them.

They test me. Break me. Push me to the edge of something I don’t understand.

Like they’re waiting for me to snap.

Or claim me.

Because whatever is waking up inside me…
it’s not normal.

It’s not safe.

And if I lose control—

I won’t just destroy myself.

I’ll destroy everything… including them.
