Diane has a way with animals. When she gets a job herding horses
her employer realizes that it is a rare form of magic and starts to
try and convince Diane to trust people as much as she trust
animals. But Diane has been so scarred and hurt by people it
seems she may never be able to really trust any human.
This is the first book in The Immortals series and IMO the second
best. The Immortals is one of my favorite series ever. It is a series
full of magic, horses, dragons, and magical beings as well as some
of my favorite fictional characters.
