Sara has been practising her new teleport powers and she’s getting pretty good! Except when she accidentally transports herself and her best friends (Georgie and Javier) and her nemesis (Jock) back in time… They’re warned not to interact with ANYONE, to make sure they don’t change anything in the future, but that becomes difficult when they’re dragged into a birthday party. They get out as quickly as they can, although not before causing some minor chaos.

But how much damage can a squashed cake really do?!? (As it turns out, a LOT.)
