Chaos, wizardry and a gang of kind-of ghosts, in this hilarious adventure from bestselling author, Steve Cole. Noah Deer's mum is an inventor, whose speciality is making things disappear. But when intruders break in to their house to steal her secrets, Noah gets caught up in a struggle - and becomes invisible! Oops. The thuggish intruders kidnap Noah's mum and, in an even more confusing turn of events, Noah realises his house is full of invisible people. From different points in history. So sort of like ghosts. Agh! Can this not-quite-ghostly gang help him get his mum back? And will he ever be able to pick anything solid up ever again? Only Noah and his new friends - AKA 'Invisible Inc.' - can save the day! Hopefully.
