Books 9-10 in Shannon Hale & Dean Hale's New York Times bestselling series take the Princess in Black on two of her most exciting adventures yet!

The Princess in Black and the Mermaid Princess: 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 very 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 the masked heroes 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 newest installment in the New York Times bestselling series is a splish-splashing good time.

The Princess in Black and the Prince in Pink: Princess Magnolia is at the Flower Festival prepping for the evening ball when suddenly she hears a commotion. Oh no! She isn’t prepared to fight a monster or . . . a grumpy emu! To her surprise, a knight in shining armor comes to the rescue, but not before the princess’s prized decorations are stomped on and destroyed. Luckily, the gallant Prince Valerian has his own secret identity—the Prince in Pink—and has been yearning for a chance to show off his special skills, with the help of some twinkle-twinkle and major glam. Glitter has been restored, but then the angry emu returns—with friends! Can the party heroes step up to save the day again? Expect the unexpected as this sparkling new entry in the New York Times bestselling series takes the floor with a flourish.
