To celebrate World Book Day, Judi Curtin has written a special story featuring the characters from Time After Time. Follow Beth and Molly on their latest adventure. Beth receives an invite to a party from a quiet classmate named Heather and Beth is not impressed. Parties are meant to be fun right? But, if parties are hosted by a quiet girl like Heather then they turn out just so awkward. Beth and Molly decide not to go. Beth's phone is a heap of junk and she wants a new one. The only problem is...she has no money to buy one. They set off on another time travelling adventure in an attempt to win a new mobile phone - this time they travel two days into the future! A journey to get a free phone becomes a discovery that Heather needs their friendship more than they ever realised. Can they fix things in time for Heather's party?
