Mo isn't exactly expecting to be asked to be Vampire Queen of Great Britain when she's cycling home from school one evening. Apparently, she is 'the Chosen One'. Aside from being uncomfortable with the idea of unelected power (not very democratic), there's the blood drinking to consider (Mo is a vegetarian), and frankly it's just not really the sort of role Mo's looking for. But when Luca, a vampire familiar, turns up, it all suddenly starts to look a bit more appealing... 12+ 'Girl Online' meets 'Buffy'.
