The BFB (Big Fat Baby) is missing! Can Rover the wonder dog and his little nephew Messi (who is actually very tidy) track her down? While Rover and co. are hot on the trail of the BFB, via Granny Mack's backpack, the post lady's basket and a plane bound for Africa, it looks like the Gigglers are about to run out of poo . . . And without an urgent delivery from Rover, how will they be able to give the Giggler Treatment to grumpy adults and help kids all over the country? Rover returns in a brand-new adventure in the bestselling series by Booker Prize-winner Roddy Doyle.
