**Could Amy and Dan's biggest enemy be . . . a friend? Book 6 in the series challenges everything you thought you knew about the Clue race.**

Fourteen-year-old Amy Cahill and her younger brother, Dan, head to the Land Down Under to discover what their own mother and father knew about the hunt for the 39 Clues. But following in their parents' footsteps brings up lost memories for Amy so awful that she can't share them . . . even with Dan.

Their blindness leads to a terrible mistake . . and the death of a hidden ally.
