Alien Prince Protector by Harlyn Moxie

I’ll keep his royal secrets… for a price.
When a missing alien prince falls into my lap, wounded, hunted, and desperate for sanctuary, I do what any queen of contraband trades would do — I begin planning my mansion on easy street.
But if this impressive alien warrior doesn’t live long enough to claim his throne, the hefty reward he’s promising in return for my help will die with him… along with any real chance I have at saving my kid brother from a living hell.
Protecting His Highness, Kam of Frage, had better be a worth all the trouble he’s causing, because if I have to trade every one of my hard-earned blackmail bribes and favors just to keep him alive…
I’m going to kill him!
