No Place For Magic (Tales of the Frog Princess #4)
by E.D. Baker
When Emma and her beloved frog-turned-prince Eadric travel to Upper Montevista to ask for his parents' blessing on their marriage, they find his homeland in chaos-Eadric's annoying little brother, Bradston, has been kidnapped by Trolls! Worse, his mother won't let Emma use magic, even to rescue Bradston, and Eadric seems suddenly a bit too fond of the girls in his own castle. With a dose of bravery and a few clever tricks both magic and not, Emma takes center stage again in this utterly charming and surprising addition to the Frog Princess series.
