Every decent character worth it's ink on paper has to go through a crucible and face adversity and challenges at every turn. I'm sure it's rule somewhere.
And Kalara certainly has her share of challenges. Another rule for awesome characters. Difficult parents who are either a) dead or b) not approving at all of the choices said character has made in his or her life. Kalara: Check.
It's not a cliché, it's simply good writing.
I like it.
