Rakarthen Academy by Clara Hartley

Three dragon fae men.
A girl who must prove her strength.
A prophecy that binds them together.

They came from a faraway land, promising a treaty, new adventures, and a place where I can fit in.
Cendri wants to break me.
Nemreth wishes to deceive me.
And I can’t tell what goes behind Aland’s mind, for his eyes are as cold as his disposition.
They’ve seduced me with their promises, and only after I enter Thesnan do I learn that the fae hate people like me. I’m here to face their test, to prove to them that dragon-kind are worthy of their acceptance.
I’m told I should run and go home. Ignore the trials of these petty folk. But I’m stubborn and I refuse to back down. A looming threat of a massive undead army is why the fae sought us in the first place. If I can’t get the alliance working, my ineptitude might result in countless deaths.
More importantly, I want to win. Running away after being made a fool by the fae simply isn’t my style. I’ll wipe those smug grins off the triad’s faces, and they’re going to beg for my forgiveness—right after I figure out how this whole magic thing works, anyway.
