Lost and Abroad

Sixteen year old Lorna could have been considered normal for a Gifted Human in her homeland of Dar Kest. She can shape shift into a mare the color of her jet black hair and her icy-silver-blue eyes. But despite being born from two very highly powerful Gifted humans, her power is hindered by headaches that have always plagued her and kept her from staying in her horse form for very long.
It is during an errand for her parents when she and her best friend, an Enchanted horse named Flare are captured and stolen away and sold to pirates on a ship bound for places unknown. It is during this journey when a sudden horrifying hurricane seems to appear out of nowhere and destroys the ship and pirates. Lorna survives the shipwreck as she floats on a portion of the destroyed ship, but not before sustaining an injury to her head.
She eventually comes to a shore which is not the shore of her own homeland and even as she fears Flare's death at sea, she has worse things to worry about as her vision is affected by the injury from the storm. But to top everything off, she soon comes to realise that this land is very different to her home and that Humans are not treated warmly in this part of the world where humans are the minority and all sorts of creatures live in their own territories surrounding her. But none despise the Humans more than the mighty Centaurs. Very few of the different creatures even get along with each other.
In this land that she learns is called Mythangdon, it comes to light that there is something far more sinister than neighboring desputes among the creatures as the very land seeks out Lorna seeking her help in defeating the threat. For while there is some magic in this land, Lorna is made of different stuff, with a far greater magic than she could ever have imagined.
