Stuck in Containment with You

One is a prince. The other, a prisoner.
Rust has been trained to hate mortal humans his whole life. Captured by a secret organization and put in a room that looks like a castle, he has his reasons not to open up. Ember was framed for a murder, and trapped here by the government. Ember was attacked by another inmate, and the gash won't seem to close. When the two meet, their lives are changed forever. Will Rust learn that not all mortals are bad? Will Ember finally find peace within this establishment? Or will they both attempt to kill each other over and over again?
