Bad Mermaids Meet the Witches: World Book Day 2019 (Paperback) Sibeal Pounder (author), Jason Cockcroft (illustrator), Laura Ellen Anderson (illustrator)

Once every one hundred years, the mermaids of the Hidden Lagoon and the witches of Sinkville get together for a party! The Top Witch greets the Mermaid Queen, who is wheeled through the streets of Sinkville in a bathtub. Mermaids Beattie, Mimi and Zelda can't wait to meet a real witch, but when Tiga is unexpectedly sucked down the plughole into the Hidden Lagoon before the celebrations even start, things start to go magically, marvellously, megalodon-sharkally WRONG. Sibeal Pounder brings together the characters from her brilliant, bonkers, bestselling Bad Mermaids and Witch Wars series for a once-in-a-lifetime World Book Day adventure.
