The Immortals quartet, by Tamora Pierce, is the story of Veralidaine Sarrasri (known as Daine), an orphan with an unusual talent: she can speak with animals.
The orphan Daine applies for a job that takes her and her trusty pony Cloud from her birthcountry of Galla to the kingdom of Tortall. Here she finds a new life and a new family, and learns that she has the magical ability to talk to animals. She makes friends with a lineup of chacters and creatures, among others the black-robe mage Numair Salmalin, a young dragon named Skysong (nicknamed Kitten), the legendary Lioness, Alanna of Trebond, King Jonathan and Queen Thayet of Tortall.
Veralidaine "Daine" Sarrasri: The main character of the quartet, she is a young woman possessing "wild magic," and has the power to speak to, heal, and shapeshift into animals. Born in the village of Snowsdale in Galla, her father is Weiryn, a minor god of the hunt who fell in love with Daine's mother, Sarra. Despite her original fear of her wild magic overpowering her, she learns to control her power. She is shown to hate Stormwings, magical creatures who prey on fear and warfare, in the first books, but later changes her mind when she realizes that Stormwings are simply what they are. She even develops a tentative friendship with a Stormwing named Rikash.
