Ruthless Blood

2022

A thrall is supposed to be a grateful, willing servant, and constant source for their Vampyre Lord. I am not willing and I despise being in his presence. The days have blurred together ever since he forced his blood down my throat. This is supposed to be illegal in society, but the laws don’t apply to the Vampyre King. It doesn’t matter how much I fight him off and refuse to bend to his will despite his blood running through my veins–it only makes him want me more. Apparently I’m an anomaly. No one has ever refused the call of a Vampyre’s blood. I try to keep my hope alive that someone will step in and right the wrongs of my injustice…But no one does. There’s nothing I can do to escape this misery. I’m paraded around in front of the King’s Lords at a banquet, freely offered as a source to whoever wants a taste. Until Vampyre Lords from distant lands threaten a war for my release from captivity. While I should fear them, I find myself drawn to them instead. They light the spark of hope within my soul that I thought was long extinguished. Perhaps this isn’t always how my life will be. Perhaps I’ll find my freedom. From the authors that brought you Monarchs of Hell and Dark Imaginarium Academy…

Ruthless War

2022

No one will ever make me bow to him again. For years, a small kernel of hope for my freedom was all that kept me alive while imprisoned by the brutal Thaician Emperor, Malakai. Now, those wishing to return me to him threaten everything I’ve fought so desperately for. This time is different, though, because they’ve underestimated me. I have far more than hope in my arsenal now, and I’m not the same woman I was under his rule. But will it be enough to make it back to the three vampyre lords who set my heart on fire? Before, I simply hoped for freedom. Now, I know there is so much more waiting for me beyond these shackles: my new home, friendships, love, and most importantly, a chance to change the world for the better. And I am willing to fight for it all—ruthlessly. \\\* From the authors that brought you Monarchs of Hell and Dark Imaginarium Academy… Ruthless Blood is book one in the Vampyres’ Source trilogy that features a strong-willed but wounded FMC and her possessive Vampyre Lords that will topple empires for her freedom.

Ruthless Love

2022

Thrall. Dhamphyr. Empress. Each is a title that has been thrust upon me, but there’s another I’ll willingly claim for myself: Malakai’s executioner. He thought he could break me…twist me into his obedient pet–but all he has done is add to the list of reasons why I’ll find him and then kill him. Of course, it isn’t that simple, and I have made many promises that I have to uphold. To bring as many of our soldiers home to their families as possible. To free the citizens of Malakai’s empire of his oppression. To unite two empires under the mantles of freedom and equality. Will my ruthless love be enough to end this for good, all while staying true to those promises? It has to be. From the authors that brought you Monarchs of Hell and Dark Imaginarium Academy… Ruthless Love is the final book in the Vampyres’ Source trilogy that features a strong-willed but wounded FMC and her possessive Vampyre Lords that will topple empires for her freedom.
