As as "adult" getting back into horses, I have to say "Falling for Eli" absolutely captured the feelings I was having as I went through the process of recapturing that dream of childhood.
And I still enjoy reading the Young Person's Fiction horse books. I've just finished up the 3 "A Circuit" books.
Also, oldie but goodies "Fly-By-Night" and "The Team" by K.M. Peyton. "The Crumb", "The Monday Horses" and "Can I get there by Candlelight" by Jean Slaughter Doty are all books that I've read over and over.
I exhausted all of the "Pony Books" in our library...now with Amazon
there's a never ending supply of them!
