Trouble at the Valentine Factory - A Seven Kingdoms Fairy Tale, #2.5

This "zany story of ingenuity and collaboration" comes "Highly recommended" by the School Library Journal. It's a buzzy love letter to kids about friendship, honeybees, troublesome cupids, and a dragon allergic to charm. Will the Seven Kingdoms be the friendliest place in the world? Or the rudest? The eleven-year-old royal Saffron twins-Princess Saffy and Prince Magellan--have to save the Seven Kingdoms from the Blackfly Queen's dangerous new magical candies!The trouble starts when the Blackfly Queen introduces a brand-new holiday guaranteed to make her the most beloved queen in the Seven Kingdoms: Valentine's Day!?!This year, Valentine's Day falls on the same day as the Seven Kingdoms' traditional Rose Monday Parade.
Instead of delighting the crowds with the usual candies, the queen has a dastardly plan. She's making Consternation Hearts with magical powers, a.k.a. rude candy hearts with messages good for every day of the year.
