Forever Love - Antonello Brothers: Immortal

For their love, eternity won't be long enough... 

Izzorah has always been a Kin—a fierce, rugged feline race—until a transfusion awakens his true nature as an immortal. When he uncovers the truth about his fiance's immortality—and his own—his familiar world shatters, forcing him to navigate a treacherous path.

To secure his place in a warrior society he never wanted, Izzorah must pass a perilous test devised by the immortal king. Succeed, and he gains acceptance; fail, and he risks banishment from his homeworld, his family, and the man who is lord of his heart.

But there's more at stake than just his own future. His lover is also the king's ex, and the king is notorious for refusing to relinquish anything—or anyone—he loves. With the odds stacked against him, Izzorah must summon every ounce of courage and cunning.

Fair test? Not in this immortal lifetime. But this king has never had to reckon with Izzorah...

A gay sci fi romance with roleplaying and a happy ever after (age gap, LitRPG).
