Winter Of The Crystal Dances by Angela Dorsey

Evy can telepathically understand horses, but she’s not sure if it’s a blessing or a curse. Her secret “gift” certainly seems to get her in a lot of trouble.

Publisher Description

When some starving mustangs wander close to the wilderness cabin that she shares with her hermit mother she knows she must help them. Her act of kindness quickly snowballs into a series of events that forever changes her life and the life of a very special mustang filly.
