The Frog-King, or Iron Henry
This is Jacob Grimm's classic fairy tale about a princess who makes a bargain with a frog to recover her golden ball, only to discover that her reluctant companion is actually a bewitched prince. Written as part of the Brothers Grimm's canonical collection of German folk tales, this story exemplifies the transformative power of promises kept and the redemptive nature of compassion. Readers should expect a whimsical yet morally instructive narrative where consequences follow broken oaths, and where magic and the supernatural serve to teach virtue.
