Valkyrie Cain's chances of survival are looking slight in the eighteenth instalment of Landy's series, as an island of sorcerers, a terrorist organisation and her own sister wreak otherworldly havoc. Magical society is about to be torn in two. With an island of sorcerers ready to cut themselves off from the rest of the world, a terrorist group enjoying unprecedented public support, and a looming showdown between her sister and the Child of the Ancients, Valkyrie Cain only has time to focus on her most immediate dilemma: the daily fight to stay alive in a place where everyone wants to kill her. This, once again, is the end.
