Author(s): H.I. Larry
Zac has to rescue one of GIB's best agents who has gone missing near the Vanishing Tomb, somewhere in the desert region of the Amber Sands. The Vanishing Tomb keeps vanishing and has ancient booby traps. Zac will need more than a bag full of super-cool spy gadgets to complete this mission and get out alive.
The author of the Zac Power series, H.I. Larry's identity remains a secret even to his publishers. Rumoured to be an ex-spy, or someone high up in the G.I.B, H.I. Larry's manuscripts (which are delivered in unmarked envelopes) are said to be based on the real-life experiences of a 12-year-old-spy.
