The Fairy Godmother Academy #6: Trinity's Book by Jan Bozarth
Trinity has always been fearless—she loves climbing and finding the highest possible points to look out over New York City. In Aventurine, she arrives just as the fairy queens are meeting to determine the location of the baby that will one day succeed Queen Patchouli as the queen of all of Aventurine. The baby can be found in the dangerous land above the clouds, the Cantigo Uplands. The only way to reach this land is to climb the mile-high pine trees of the Cloud Forest. Trinity quickly volunteers for the mission. Armed with a kite to help her soar up into the clouds, Trinity's bravery will be tested as she faces monstrous enemies, makes strange new friends, and discovers her own special brand of magic.
