The graphic novel series Pablo and Splash, which launched in 2024, is Sheena Dempsey's first work as author and illustrator. It grew out of a webcomic she created during the pandemic lockdowns that featured her and her husband as penguins! Sheena is an illustrator whose books have won several awards including the Sheffield Book Awards for Yoga Babies by Fearne Cotton and Surrey Libraries' Children's Book Award for Dave Pigeon by Swapna Haddow. She has also been shortlisted for the Sainsbury's Children's Book Award. Sheena was born in Cork, Ireland, but now lives in Folkestone, Kent, England.
