Antrax

In Ilse Witch, Terry Brooks started a new Shannara series already, his most successful. Now in Antrax, as the crew aboard the airship Jerle Shannara is attacked by evil forces, the druid's protégé, Bek Rowe, and his companions are pursued by the mysterious Ilse Witch. Meanwhile, Walker is alone, caught in a dark maze beneath the ruined city of Castledown, stalked by a hungry, unseen enemy. For there is something alive in Castledown. Something not human, and old beyond reckoning. It covets the magic of Druids, elves and even the Ilse Witch. It is Antrax: a spirit that commands ancient technologies and mechanical monsters, feeds off enchantment and traps the souls of men.

With the Jerle Shannara under siege, the Ilse Witch finds herself face to face with Bek, a boy who claims to be the brother she last saw as an infant now a young man, who carries the Sword of Shannara and wields the magic of the wishsong...

Return to the world of the Four Lands, where creatures drift up from the earth like mist, a hypnotic song can kill, a sword can cut through a veil of lies and one man, the true heir of an ancient magic, must choose between betrayal and redemption.
