A horse is born on the galleon Sailina in the middle of the wild ocean. The galleon is sailing to the new world by men seeking gold. They name the horse Estrella and it's born to run, but she's kept in a sling and her hooves can't touch the ground. She's born for the land, but all she know's is the rocking of the sea. She's born to be free, but she and her mother are owned. Then the men decided that the weight of the horses is slowing their ship down so they throw the weakest and oldest horses into the water. If you love horse books you should read this book.
