Runic Light (en Inglés) - Bobby Burkey

In the city of Charst, humanity survives behind an ancient magical barrier. Beyond it, twisted nightmarish creatures known as the Dark have already consumed the world.

Prince Karth has always known his fate-he will be king. The only heir to the throne, the burden of humanity's survival rests on his shoulders. But ruling the last city is more than a title, and as the Dark press ever closer to the barrier, Karth must prove he is more than the crown he was born to wear.

Beyond those walls, survival is a sentence.

Gwen knows that better than anyone. Exiled for daring to steal from the king's own castle, she has been cast into a world where the Dark rule and mercy doesn't exist. It will be a fight to stay alive-and to outrun the mistake that cost her everything.

And in a world already lost to darkness, survival may demand more than either of them is willing to give.

The last city stands-but for how long?
