The first three adventures in the Frog Princess series:

Book #1: The Frog Princess
Princess Emerelda is not exactly an ideal princess. Her laugh is like a foghorn, she's always tripping over the royal furniture, and she hates Prince Jorge whom her mother would one day like to see her marry. But things are about to change as she finds the frog of her dreams -- but when she kisses him, she turns into a frog! Just one kiss, and her whole life turns upside down in this deliciously original, hilarious and fast-paced fairy-tale adventure.

Book #2: Dragon's Breath
Emma and Eadric have no sooner turned back into humans (from being frogs) than Emma's mother is in a panic, Aunt Grassina is distracted because she's found her true love turned into an otter, and Emma's magic is so out of control she sends herself to the dungeon by mistake. The neighboring kingdom has chosen this moment to attack, and if Emma can't get Grassina's mind back on protecting the kingdom, life as they know it in Greater Greensward will be in peril. From underwater sea monsters to fire-breathing dragons, this witty pair of young friends manages to sweet-talk, cajole, and race their way to victory. But when it looks as if everything will finally work out, disaster strikes, and Emma finds that magic is not enough-it takes real bravery and a strong, new friendship to succeed.

Book #3: Once Upon a Curse
Many years ago a slighted fairy placed a curse on a beautiful young princess--a curse that caused her and all her female descendants to turn into mean, ugly witches if they ever touched a flower after turning sixteen. Now, Princess Emma, who is about to turn sixteen herself, is determined to break the spell once and for all. Emma travels back in time to the day the curse was placed on her ancestor in the hope of preventing the curse from being cast. Unfortunately she isn't successful in her efforts, but she does learn how to break it. Armed with this knowledge, Emma returns to her own time full of hope. But disaster ensues and Emma is about to give up completely--until true love shows itself in the most unexpected place of all.

With a bit of courage, a pinch of luck, and of course, a healthy dose of magic, Princess Emma charms her way through the third hilarious adventure in the Tales of the Frog Princess series.
