Blightspawn

Bethany Sweet is dead. So no wonder she's surprised to wake up again. Only this isn't Earth and the beautiful body she's wearing isn't hers. And it's been kidnapped. If the murderous assassin tracking her wasn't bad enough, she realises she's been summoned for a vicious and bloody sacrifice - one that will stop a brutal monster from destroying the world. Beth can save thousands of lives, prevent mass destruction, but to do it she has to die. And she's done that once already. She's not in a hurry to do it again.
