Fantasy coming-of-age trilogy about a boy in a small village who had healing powers, but had to hide them or he would be hunted down. He meets a girl who is later revealed to be a shape shifting dragon and they go on to discover he has more powers then he realized.
I remember a lot of little details, like he has a symbol in his eyes that signifies he has special powers, and that they are working to overthrow a kingdom that is tyrannical. I think the girl's name is maybe Kahlia and that the boy had red hair.
This was in English, and the first two books were bundled together in a single volume. The cover was black on the edges with a red background on one side and blue on the other. I seem to remember crossed weapons, maybe swords or axes, in the center. I read it about 4 years ago but am not sure how long it had been out at that point. Style was Young Adult I think.
