London, 2004. Harriet is a vampire, brought back from death and forced to drink the blood of those still living. She fights the Court of the New Sun, a cabal who rule Britain's shadows and use the magic of the Keeping to enslave the minds of thousands. With her comrades in the Unbound by her side, and untapped powers in her hands, Harriet has waged her war for centuries. But with each year, the Unbound lose ground, and Harriet's connection with the human she once was slowly fades away. But then, the unthinkable; an operation goes south, her attempt to escape is a failure, and Harriet finds herself abducted and Kept by Soteris, the Court's youngest and most promising 'Keeper.' With her free will overridden, Soteris hopes to craft a weapon from her powers that can end the Court's war. Unless the Unbound can rescue her, she's at the mercy of his destructive, unyielding, egotistical whims. But there's more than meets the eye in this fiery young monster; an ambition Harriet quietly envies, and a connection to the human world she's almost entirely forgotten. Will her friends be able to save her? Can she resist the sheer force of Soteris' will? Or will she listen to the siren's song, and give up her freedom, her mission, her past, for an even greater dream:The chance to become human
