Sarah Jane Smith inhabits a world of mystery, danger and wonder; a world where aliens are commonplace and the Earth is under threat; a world that Maria Jackson - a seemingly ordinary girl - can only dream of, until she moves in next door. Nothing will ever be ordinary again. In the first adventure, a new drink named Bubbleshock is taking the world by storm. When Maria attends the factory tour with her new friend, Kelsey - she's plunged into the sinister world of Bubbleshock and the mysterious Mrs Wormwood. There's something terrible behind the hype - something Sarah Jane's interested in too.
