Paula Harrison is the author of the much-loved The Rescue Princesses and The Secret Rescuers series. She wanted to be a writer from a young age but spent many happy years being a primary school teacher first. She finds inspiration in lots of things from cloud shapes to snippets of conversation.

She loves sandy beaches and eating popcorn. She lives with her husband and children in Buckinghamshire, which is nowhere near the sea. Whenever possible, she packs her family into the car and journeys far and wide to find a sandy beach where she can paddle in the waves.

Olivia Chin Mueller grew up in a small town in Connecticut, USA, and now lives in Rhode Island. She attended the Rhode Island School of Design and graduated with a BFA in 2014.

When she's not illustrating, Olivia loves playing with her cats, sewing and felting, and collecting cute toys and nail polish.
