Kensy and Max 3: Undercover by Jacqueline Harvey
Kensy and Max are back in London for no time at all before things begin to heat up – quite literally. As a result, Granny Cordelia ships them off to Australia on an undercover mission. The twins find themselves planted in a posh Sydney school where first appearances prove to be deceiving.
What seems like a straightforward assignment turns into something so much bigger. Kensy and Max must employ all their spy skills – the fate of their parents, and who they’ve been searching for, depends on it.
