Is Onyx Storm The Last Book In The Series By Rebecca Yarros?

For seventeen years, I believed I was nothing, Iris Delta, the unwanted orphan tolerated by a pack that saw me as a burden. The Maxwell quad Alpha heirs made sure I knew my place, tormenting me with cruel words and vicious pranks. I was weak, worthless, invisible. I was wrong about everything. On my eighteenth birthday, Alpha Maxwell reveals the truth that changes everything: I'm Seraphina Blackthorne, the last heir of a bloodline thought extinct. My parents didn't abandon me—they were murdered by the Northern Alliance, who believed they'd eliminated every trace of Blackthorne power. They were wrong, too. The moment my wolf Diamond awakens, the mate bond snaps into place with the four men who made my life hell. Fin, Brent, Kane, and Liam—my tormentors are my fated mates, four pieces of one soul that can only be completed by me. Their cruelty wasn't hatred; it was a fractured soul recognising its missing piece and lashing out in fear. But the Northern Alliance isn't finished. They've come to eliminate the last Blackthorne before I can claim my birthright. What they don't realise is that I'm not just the last heir, I'm the strongest Blackthorne born in three centuries. When divine justice flows through my veins and ghostly wolf spirits answer my call, they'll learn what happens when you try to destroy something the goddess herself has chosen to protect. The Blackthorne line has returned. And this time, we're not going down without a fight.

In a world where the moon shattered and the strong devoured the weak, Neoma Solstice is nothing. A scentless Null. A ghost. A mistake. Until the day she saves a dying Lycan warrior with a touch, and her secret is revealed: she's Void-Born, the rarest mutation in existence. The same power that makes her invisible makes her invaluable—a living weapon that can cure the incurable Feral Rot plaguing the Lycan Ascendancy. Captured and collared, Neoma is forced to serve as "Tether" to Unit Vanguard: four elite soldiers on the brink of madness. Barzil, the ruthless Commander who sees her as a mission. Wolfy, the cold Tactician who sees her as a puzzle. Viggo, the feral Berserker who sees her as salvation. Guller, the fallen Priest who sees her as redemption. They own her contract. They control her life. They swear she's just a tool. But tools don't make their masters kneel. As Neoma's power grows, so does the threat she poses to the regime that enslaved her. When the prophesied Blood Moon rises, she'll have to choose: remain the Ascendancy's battery, or become the Void that devours them whole. Some bonds are forged in blood. Some in magic. Theirs was forged in desperation—and it might be the only thing strong enough to save a dying world.
