Dark Prince's Mate

I thought nothing was worse than dying. Then I discovered there are things that hurt an awful lot more than chemo-like getting your heart trampled on by the insanely powerful superhuman prince who claims you're his mate. Right after we consummated the mating, no less. Well, he can have a nice life. The moment an opportunity presents itself, I'm out of here. I just need to locate someone who'll portal me back to Earth before he finds me.
