Bloody Hell

Mercy Brown has already died twice: once when a vampire turned her, and again when her father tore out her heart to save her. A mentor's magic bound what remained of her to her brother's soul, and now zealots from the Order of the Morning Dawn hunt her across a century and a half of history. To save him before they find him, Mercy must descend into hell itself and bring his soul home. It opens the Legacy of a Vampire Witch series.
