The Last Constantin — Alydia Rackham

Christmas Eve, 1848. Young Quinn Campbell and his best friend Agatha have been kidnapped. Their captor, Dmitriy Gavrilov, is cruel, ruthless--and a vampire. Thus begins a treacherous journey through ice-locked Europe, toward a castle in the depths of Romania, and a mysterious ruler at the heart of a thousand-year war. Now, Quinn and Agatha are caught between immortal factions, and Quinn must face the truth about all of them--and his own lineage--if he is to save his own life, Agatha's, and indeed, all of Europe.
