Is 'Greythorne' Part Of A Book Series?

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.
