The Exchange, or a Marriage of Convenience (en Inglés) - Olena Shevtsova

To escape the arranged marriage my mother and stepfather had planned for me, I accepted the rector's offer to take his fiancée's place in a student exchange program.

As if that were not bad enough, I, a future healer-mage, ended up at the Dark Academy. And not just anywhere in it, but on the combat faculty.

Just as I had feared, a light mage was anything but welcome there, and one disaster after another led me into yet another mistake...

I made another bargain.

This time, with a member of the narg race.
