The adventures of Anya, a second princess, out to disenchant the prince whom her sister Morven had been in love with, until her stepstepfather had not only turned this prince into a frog, but produced another prince to lure Morven's heart away. (Not that that's too difficult.)
And he threatens to send Anya to school at a place so far away that she's in danger merely going there.
Fortunately, the failed sorcerer who is the librarian had a recipe for lip balm that makes other kisses effective. They accidentally use it on another enchanted frog, though, so Anya must go on a quest to ready the balm.
It involves a transformed otter, how druids retire, whether a small boy is a thief, witches who need onions, what the kingdoms were like when unified as one, the differences between sorcerers and wizards, why it's said that a Garden is a prison, and more.
Enjoyable adventures, leavened with lightness.
