Martha Mumford has loved children's books forever. Her mother was a librarian which gave her access to a wonderful array of books from a very early age. The Royal Baby's Big Red Bus Tour is her fourth children's picture book with Bloomsbury. Martha loves baking, patchwork and has a mild obsession with interiors magazines (although she freely admits that the ideas she has found therein have yet to be translated to the interior of her own home!). Martha lives in Berkshire with her husband and young daughters.

Ada Grey has worked as a successful illustrator of cards, gifts and stationery for many years, and she is very excited to have developed a strong and appealing new illustration style for picture books. Shhh! Don't Wake the Royal Baby was her first picture book for Bloomsbury, and marked the beginning of a brand-new, successful series. Ada also illustrated Santa Baby by Smriti Prasadam-Halls and also published by Bloomsbury. Ada lives in Brighton with her family.

It's a beautiful day, and the Royal Family are sunning themselves in the Palace Gardens. The royal babies' grandad is even having a bit of a snooze - what bliss! When all of a sudden --
BEEP BEEP! BEEP BEEP!
It's the Big Red Bus, and it's come to take the Royal Family on a tour of London! With so much to see, the city is their oyster, with the Royal Family hopping off at the Natural History Museum, London Zoo, the London Eye and Tower Bridge. They even ride a water taxi to Greenwich, before it's finally time for - you've guessed it - a spot of shopping!
The Royal Baby's Big Red Bus Tour of London is the next installment in the brilliantly bonkers and fabulously funny Royal Baby series that's perfect for fans of London, the Royal Family and crackingly good stories.
