Never a conventional princess, Harriet becomes an adventurer after learning she is cursed to fall into a deep sleep on her twelfth birthday, but after two years of slaying ogres, cliff-diving, and more with her riding quail, Mumfrey, things go awry at home and she must seek a prince to set things right.

"It is Princess Harriet Hamsterbone to the rescue when Heady the hydra's egg is stolen, but her search leads her to a castle accessible only by a rat with a very long tail"--

"When a fairy godmouse forces Whiskerella to wear glass slippers and attend balls night after night in search of a happily ever after, it's up to Princess Harriet Hamsterbone to break the spell and save the day"--

Harriet Hamsterbone sets out to reverse the curse on twelve mice princesses who are forced to dance all night, every night.
