Prince Sky was destined to become the greatest king his people had ever known...and to spend his life without a mate. Nani, an omega assassin raised among vampires, had already rejected the mate fate gave him and wanted nothing more to do with wolves or their cruel goddess. But when their paths cross, and fate so cruelly tests Nani, the unmated prince and him are drawn together in a way neither of them can explain. The goddess promised Sky would rule alone. She never promised he would never fall in love.

Nani is a professional assassin with a flawless record. Marrying Sky was supposed to be nothing more than business. It was his way to access money, influence, and protection, all wrapped in the safety of a husband who knows nothing about the blood on Nani's hands. Except Sky knows. He's known from the beginning. Instead of confronting Nani, Sky does what he's always done best, he takes control behind the scenes. And Nani is none the wiser. He believes he's living a double life, slipping out at night while his husband sleeps peacefully beside him. He believes Sky is naive and oblivious. Sky lets him believe it. But when a job goes wrong and lines begin to blur, Nani starts to realize something is off. The cover-ups are too clean. The enemies vanish too easily. The danger never quite reaches him. And the most terrifying truth begins to surface... Nani isn't the deadliest thing in their marriage. Sky is.

When Nani's sister gets a work contract overseas for a few months, he steps in to care for his six-year-old niece, Lily. He thinks he can balance everything; he's cleared part of his modelling schedule...everything works out at the beginning. But then a fire breaks out at Lily's school. And that's where he meets him...Sky, a calm, serious, stupidly handsome firefighter holding Lily in his arms. Lily clings to Sky like she's known him forever. And just like that, Sky catches Nani's attention. #SkyNani AU

Nani had managed to survive three years at his marketing job without anyone catching on to his small, harmless lie... That he was married, and that his imaginary three-year-old was the reason he occasionally left work early.
