'Witty, wise and wonderful . . . Such fun!' Miranda Hart. When thirteen-year-old Tabitha's parents split up, she's forced to move down to London with her mum and brother. Sounds cool right? Well there's just one teeny tiny hitch. They're moving in with Gran . . . Mental, very much NOT cool Gran, who talks to (AND FOR) her knitwear-adorned dog Basil like he's the son she never had. Worse still, her mum has decided to start writing an embarrassing blog (much of it about her teenage daughter) and her younger brother Luke's favourite pastime seems to be 'annoy Tab as much as humanly possible'. All this embarrassment is particularly bad news as Tabitha has given herself a mission for her new school: to be the coolest, most popular girl there! Despite her family's best efforts, things get off to a good start as Tab quickly makes friends with A'isha and Emz (and manages to avoid total losers like Grace). She seems to be on the rise and rise - even meeting cute dog walker Sam whilst out with Basil - but then disaster strikes. Is Tab about to find out the real cost of popularity?
