Greg James drops by This Morning fresh from his Radio 1 Breakfast Show to chat about his ninth children's book, The Kid Who Fell Through Time, co-written with Chris Smith. He reveals how he and Chris brainstorm entire plots in the pub doing character voices, explains why they write books meant to be read aloud, and does hilarious impressions of evil Emperor Crag and other characters from this time-travel adventure about a boy named Angus who travels via wonky shopping trolley to ancient Egypt, Rome, and Shakespeare's era.
