Here’s the excerpt I found so you can compare the two.

One spring day the good young girl went to the well in the forest. There she met another old woman, far more frail and feeble than her mother. The woman asked her for a drink of water. The girl replied, “Of course, old mother,” and dipped the bucket for her. After quenching her thirst the woman said, “You are so kind and sweet and beautiful that I will bless you for it. Each time you open your mouth, a lovely flower or a precious stone will drop from it.” And it happened, for the woman was a fairy.

The girl ran home to tell her mother and sister. Soon knee-deep in emeralds and roses, they believed her. The miserly termagant of a mother chased the elder girl into the forest to seek her fortune, too. The old woman was still at the well, and she asked the elder girl for a drink. But the willful girl said, “I certainly will not fetch water for someone who has nothing better to do than sit on wells! Don’t you have a home to go to?”

The old woman stamped her foot and said, “Oh! You are so mean and stubborn and ugly that I will curse you for it. Each time you open your mouth, a horrible insect or an ugly swamp creature will drop from it.” And it happened.

The girl ran home, weeping foul creatures. The shock killed her mother dead. Then a prince rode by and spoke to the younger sister, who was also very beautiful. When she answered kindly, and in gems, he determined right then and there to marry her as a present to himself (her sweetness) and his kingdom (the gems). They lived happily ever after.

Driven mad by her curse, the elder girl ran away to a corner of the forest and died all alone. And since she was always so ugly and quarrelsome, no one missed her.

Ummm, he fell in love with her because he felt she was talking to him through her music and the spell was broken

Publishers Weekly Review: /* Starred Review */ British author Hearn makes a memorable American debut with this tightly woven tale of a witch hunt. She pits 15-year-old Grace, the daughter of a hypocritical Puritan minister, against Nell, the granddaughter of a midwife and healer who has taken Nell as her apprentice. The novel alternates between the dangerous times of the English Civil War during April 1645–January 1646, and the confessions of Patience Madden, the minister’s “simple” daughter, from the New World in 1692. Patience reveals how she colluded to throw fits in order to conceal Grace’s pregnancy and to damn Nell as a witch. Hearn effectively contrasts the sanctimonious minister and the creepy town “Watchers” (“women who like nothing better than a good hanging”) with the magical, impish piskies and fairies that populate the countryside plus the knowledge of herbs and spells (offered with a liberal dose of humor) passed down to Nell. Hearn places actual historical figures (including Matthew Hopkins, “Witch-finder General”) among her stellar cast and, through Nell’s scenes, reveals prevailing attitudes toward religion: “The little church is full…. There are those who truly believe; some who are trying to; and a few who never will, but need to pretend, for the look of it.” Those in the know will not be surprised when Patience’s recollections lead to the doorstep of the Salem witch trials, while others less knowledgeable may be inspired to find out more. With its thought-provoking perceptions about human nature, magic and persecution, this tale will surely cast a spell over readers. Ages 12-up.

Kirkus Reviews /* Starred Review */ The year is 1645, and Nell, the village “cunning woman’s” granddaughter, has been learning the healer’s trade, desperately hoping to conceal her grandmother’s increasing senility until she is able to take her place. At one margin of her world lurk the piskies and fairies that represent the old ways she follows; at the other, the forces of modernization in the forms of the Puritan minister and the English Civil War. The spikily independent Nell’s conscientiousness brings her into contact and conflict with the minister’s daughters: Grace, unmarried and pregnant, and Patience, her simple sister, whose imperfect apprehension of the tensions swirling around her form an eerie counter narrative, taken down during the 1692 witch panic of Salem Village. Hearn develops each character with exquisite care, the month-by-month narration ratcheting up the tension as Grace’s belly swells and the minister casts about for scapegoats. Even though Patience’s retrospective account, appearing as it does in the chapter breaks, lends an air of dreary inevitability, the old Powers have a way of enforcing their own rules. The result is twinned endings, one eminently satisfying, the other satisfyingly unsettling. Tremendous. (Fiction. YA)
