Artemis Fowl and The Last Guardian

Is this the end for Artemis Fowl? Opal koboi is back, and up to no good. A bit of world-domination here, a little light annihilation there. Some power-crazed pixies never change. But now Opal plans to wake the spirits of some very deadly, and very angry, long-dead fairy warriors, before releasing an ancient spell to wipe out all human life. Artemis, Butler, Holly and mulch must make a final stand against Opal and the end of the world. But who will be willing to make the ultimate sacrifice to save humanity?.
