The Princess in Black and the Science Fair Scare

It`s mayhem at the science fair! A squishy goo monster is a challenge for the Princess in Black -- but luckily some science-loving princesses are on hand to help. Princess Magnolia is excited. Excited and nervous. She`s going to the Interkingdom Science Fair today to present her poster about seeds and plants, and when she arrives, she sees that her friends are there too! Princess Honeysuckle made a mole habitat, Princess Sneezewort has built a blanket fort, and Tommy Wigtower has a talking volcano that`s saying 'EAAAAT!' Wait, what? A surprise goo monster makes this a job for the Princess in Black, and the Princess in Blankets is on the scene to lend a hand. But will two masked heroes be enough to save the science fair? A little scientific problem-solving -- and a lot of princess power -- will make the sixth entry in the New York Times best-selling series a smash hit.
