Mina, Reema and Mobeen can’t wait to go on their school trip, an overnight stay at Shiremoor Oaks Adventure Centre . . .

until somebody spooks them with stories about Bertie Blackteeth: who haunts the woods, who sharpens her toenails with twigs, who is waiting to skewer her next unfortunate victim all over with cheese-and-onion crisps! With Bertie Blackteeth lurking and the school bully seeming to have become the teacher’s pet – this trip will test their friendship, courage and love of potato chips to the limit.
