A great book for a 6+ year old girl who loves horses

[Enid]

I bought this for dd1 for christmas. We read the last chapter last night and it was sooooooooooooooo good. Quite mournful and thoughtful and slightly spooky.

The Enchanted Horse by Magdelen Nabb

Can anyone tell me the name of a recent book about a girl who goes to boarding school??
