“Pure adventure fun.”—Kirkus Reviews

Natascha and Max Raffifi, recently orphaned and new to England, are adjusting nicely to their new life. Anything’s better than being on the run. Especially being reunited with their little black-and-white dog named Grk and living with their friend Tim.

But one afternoon, Natascha sees a familiar name in the newspaper headlines. The infamous Pelotti brothers are on a crime streak in Brazil. This gang of criminal masterminds has only ever been captured once—by her father. To avenge his senseless death, Natascha and Max know they have to act.

Setting off in the middle of the night, the Raffifis, with Tim and Grk at their side, arrive in Rio de Janeiro ready for action. But when Tim and Grk are separated from their friends, they find more trouble than they bargained for.
