Born a Changeling in the gleaming, ordered world of Polli-Nation, Nanda’s body betrays every expectation, shifting without warning between male (Nate) and female (Polli) forms.
In a society obsessed with control and perfection, that volatility is both curse and rebellion.
All Nanda wants is peace, belonging, and purpose, but instead comes a mission wrapped in danger.
Sent as a junior aide to the theocratic Sylvan Empire, where Nates rule and Pollis are possessions, Nanda becomes both ambassador and provocation.
Under the erratic genius of Lord Vincent and the cold vigilance of his bodyguard Saul, the mission spirals into deceit, blood, and betrayal.
To survive, Nanda must evolve beyond obedience and expectation, becoming something the world cannot define or destroy.

I was forced by my father to fulfill an arranged engagement with an Alpha I'd never met face-to-face. Pushing open the jewelry store door, I found my fiancé Kane spoiling his childhood sweetheart Briar, who was trying to snatch my mother’s ring. "Security! Get this stray out of here!" Briar screamed, pointing at me. When I revealed my identity, Kane sneered coldly: "What bullshit pact? I would never marry a woman like you." Briar snatched the ring and threw water at my face: "Kneel down and beg me to give it back!" When I fought back, Kane exploded in rage: "How dare you touch my woman? Hold her down!" Four warriors pinned me down as Briar laughed cruelly: "Let everyone see this delusional bitch who doesn't know her place!" They stepped on my hand while Kane watched coldly, even urging her on: "Hurry up, let her learn her lesson." Just as she was about to chop off my finger with a knife, the door suddenly burst open—"Do you have any idea whose daughter you're humiliating?"

"Who would want a woman like Hazel?"
On the night before our wedding, my fiancé Randy said this in front of everyone.
I stood outside, listening silently before walking away.
Sure enough, at the wedding, he abandoned me to save my sister who was jumping from a building.
