The Princess in Black and the Mermaid Princess

There’s trouble under the sea! Can the Princess in Black and her new mermaid friend put a stop to a big blue kraken’s shenanigans?

The Princess in Black and her friends are enjoying a day of sun and sea on Princess Sneezewort’s royal boat when a real, live mermaid princess emerges from the waves! Eeeeeee! Princess Posy needs their help protecting her cute sea goats from being eaten by a very greedy kraken. But the princesses and the Goat Avenger quickly realize that fighting underwater can be tough for land dwellers, and only the mermaid Princess Posy can save the day. Can they help her learn that being a princess means more than just being nice—it means speaking up? An ode to using your voice (along with a kelp-tree swing or two), this installment of the New York Times best-selling series—now in paperback—is a splish-splashing good time.
