Meet Isadora Moon's mermaid friend, Emerald! Emerald is learning how to be a mermaid princess, but there are just so many rules. She loves having fun with her friends and exploring her underwater world with her pet octopus, Inkibelle, she doesn't want to be stuck in the palace with everyone looking at her and checking that she's doing things the proper, royal way.

In Emerald and the New Arrival, Emerald's mum is expecting a baby and there's so much to do before the big day! Everyone is excited but Emerald can't help feeling a little...unsure. What if she gets woken up at night by all the crying? And what if Mum and her step-dad Auster are too busy with the new baby to think about her? But family life is full of surprises, and Emerald is about to find out that being a big sister is a very special thing indeed.
