Valkyrie Cursed by Rosie Wylor-Owen

Rowan McQuaid should be dead. Valkyries don’t survive vampire bites. But after releasing a tomb full of rabid vampires, Rowan is still breathing. Her survival means one thing: somehow, she is immune. When witches are slaughtered in their homes, Rowan discovers the vampires are hell-bent on killing the descendants of those who imprisoned them. And every drop of blood spilled is on her hands. Forced to team up with the mysterious vampire Nate Hallewell, Rowan must find and stop the rogue vampires before they kill every witch in south east England.
