Two of Zac's most aerial missions in one book: Sky High and Lunar Strike! In Sky High, a piece of top-secret GIB technology has been stolen, and Zac Power has to get it back. Blasting off towards a secret hide-out in the sky, he faces his strangest enemy yet. Then, in Lunar Strike, Zac is rocketed into outer space to stop the sabotage of a charity rock concert. An enemy agent is out to steal billions of dollars in donations, and will stop at nothing to get them. This is Zac's toughest mission yet - can he handle the pressure?
