Is 'Butcher Blackbird' Part Of A Series?

I found out my husband of three years had cheated on me and his mistress is the one who told me—because he didn’t have the balls to do it himself. I move out and get a new apartment, a job as a bartender, and try to move on with a broken heart. I wonder where it all went wrong, if I hadn’t been enough for him, if I’d been stupid for marrying him in the first place. I’m at work one night when he walks inside—the most beautiful man I’ve ever seen. He sits at the bar and a forest fire burns between us. I was depressed the moment before he entered, but the second I look at his blue eyes, I forget the dumpster fire that my life has become. I invite him back to my place and it’s the most passionate night of my life. I expect to never see him again. I just want him as an anti-depressant—but he wants me all to himself. I just got my heart ripped out of my chest so I want something easy and no-strings-attached, but he wants all the strings because he’s hooked. I don’t get much of a say in the matter, and that’s not surprising when I learn why—because he’s the Butcher. The crime lord of all crime lords, the boss that overshadows all of Paris, that makes everyone abide by his rules—or pay. And now I’m his.

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.

Four years ago, I watched Alpha Adrian slaughter my parents and destroy the Nightfall Pack. Everyone I loved turned to ash and blood that night—everyone except Asher, my best friend who pulled me from the flames. Now I'm infiltrating his pack as a slave vengeance in my heart. I've waited four years for this moment. Four years to get close enough to kill him just as he killed my parents. But fate is a cruel bitch. The mate bond snapped the moment I entered his quarters, binding me to the one man I swore to kill. My body betrays me, craving his touch while my mind screams for his death. And when Adrian finally feels it too, when he discovers I'm the last survivor of the pack he destroyed, everything changes. He says he needs me. That I'm the cure to an ailment slowly killing him. I need him too—he's the only one who can heal my broken wolf and help me shift again. The bond doesn't lie. And neither does the truth I'm starting to uncover about that bloody night. My heart is torn between my best friend who saved me and the mate who killed my parents and holds the key to making me whole again. [THE CURSED BLOODLINE SERIES BOOK I]

In a world where werewolves rule from the shadows, Rhett Blackwood is king. To hold his empire, he must forge a blood bond with a ruthless assassin who would rather kill him than kneel. But when one act of violence awakens a bond written in fate — and blood — they are thrown into a brutal war where love may be their only weapon… and their greatest curse.

I’m trained to do one thing: kill. I was put into a school where the concepts of love and forgiveness were treated as weaknesses. When I graduated, they told me I’d be lucky to survive; now I’m the best of the best and the person who gets the job done no matter what. I’ve assassinated Presidents, housewives, Navy SEALS and more shifters than I can count. I have more kills than anyone in my business, so when a new order comes in to kill Alpha Gideon, I take it without a second thought. ​He’s a job like any other, but during my scouting, I see something I’ve never seen before. Alpha Gideon isn’t a tyrant or a bully; he’s kind to his Pack. I start asking questions, which is when everything goes to shit. My signal is found, and for the first time in my life, my target has me in his sights. I expect pain and maybe even death, but Alpha Gideon treats me like a welcomed guest; his warmth and kindness open up something inside of me that I didn’t know I had. I should kill him before he changes me completely. I tell him I’m cold and heartless, and he laughs. Loving a mark has never been done, but no matter what I do, every touch sets me on fire and with each longing glance, my past becomes a distant memory. I’m ready to put everything I was aside to stay with Alpha Gideon when the call comes in; my fellow assassins have been called. The bounty on Alpha Gideon has been doubled. I have two choices: protect the man who has opened up my heart or kill the target and get the job done.
