Book 3 : Tara Duncan, The Cursed Scepter (unofficial translation)

Beware as this summary contains major spoilers on the first two books

Tara Duncan, now heir to the throne of Omois, doesn’t have a minute to herself. Obliged to comply with protocol and the high expectations the empire has of her, she really does not have the time to resolve murders. And yet, someone just killed a zombie in her palace. And to kill something that’s already dead, you’ve got to be tough! Tara doesn’t take it lightly, as it seems that nonspells (those without magical powers) have created a terrorist organization to take over spellbinders! Seeing the situation, it is just a demon’s attack away of chaos. And it may as well be on its way…
