Afterglow — Eve Paludan

What would you do if everything - and everyone - you loved was taken from you? Rand Sebastian, who is now a trained vampire hunter with the Brotherhood of the Blade, faces dangerous challenges when a missing member of the Sisterhood of the Scythe returns to the castle after a long disappearance. There's just one problem: She's now a very dangerous vampire, and she's asking for sanctuary. She also reveals intel that leads Rand on a mission to Romania to see if his kidnapped daughter is there. Planning a one-man invasion, Rand is stunned at what he discovers - it will take all of his courage and training to go up against the most evil vampire who ever existed. Afterglow is the second book in the Brotherhood of the Blade Trilogy.
