The Royal Palace is in chaos yet again - not since the Royal Baby's birth has there been so much excitement! Why? Well it's the Royal Baby's first birthday, of course, and the palace is awash with activity!

There's the cake to think about, balloons, presents - and don't forget the bouncy castle and the Royal Baby's favourite game of Pin the Tail on the Corgi. The Queen may even do a spot of parachuting - it is a special occasion, after all.

Busily brilliant and fabulously funny, Happy Birthday, Royal Baby! is the must-have picture book, perfect for all little ones.

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. Shhh! Don't Wake the Royal Baby is her first children's picture book and she is delighted to be working 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 now she is very excited to have developed a strong and appealing new illustration style for picture books. Shhh! Don't Wake the Royal Baby is her first picture book for Bloomsbury. Ada lives in Brighton with her family.
