Witches really and truly do exist... and Merfolk and Sirens too. For Moira Gordon the magical world that was once stories at bedtime now is in fact, very much real.

But what happens when a street fight breaks out and the little glass vile she finds contains more than just water? Who is that mysterious woman casting those evil vile spells? Why are there so many people after her?
