Royally Flocked by Arden Steele

Heir to the throne of the elven court, Prince Orrin Nightstar has enough on his plate without an everchanging Guard. Having lost a record number of Guardians to the wiles of love, he’s beginning to think he might be cursed, doomed to lead others to happiness while never finding it for himself.
It could be worse, though. He could be mated to the Guardian of the Underworld.
Erus—not Eros, thank you very much—hasn’t guarded the iron gates for millennium. It’s cold. Dark. Lonely. And frankly, boring AF. Besides, why should he limit himself when he can outsource the job? Instead, he devotes his time to overseeing the Guardians who protect the royal families.
And someone is screwing up the system.
He never expected that someone to be his own mate. Nor did he foresee the chain of events their meeting would set into motion. After thousands of years of playing by his own rules, the consequences of his arrogance are finally catching up to him.
Now that he has Orrin, the stakes are even higher, and unless he can restore order to the Underworld, his new mate will be the one to pay the price.
