The Mad Machines of Mundara: The Third Book of Dubious Magic (Paperback) (ISBN-13: 9780994617460)

Held captive on a small island in Bass Strait, unlikely wizard John B. Stewart faces a fight for his sanity and his very existence. A ruthless Russian scientist wants to tear the wizard's power from his mind, and the life from his body for his own unbelievable purposes.

John B.'s friends have to find him before they can save him. Even if they do locate him, there are those who would kill rather than give up their secrets.

Some of the mystery of John B.'s past will be revealed as dubious magic confronts the fringes of science.
