Help needed with title of book please

[inuite]

I am trying to find the title and author of a book I read ages ago and thoroughly enjoyed. I would like to re-read the book but can't for the life of me remember the title.
It is about a horse, is quite whimsical and has a title a bit like
"Sunburst" or " snow burst"
Any help would be gratefully appreciated. Thanks.

Bit more content would possibly help...

Try the booksearch function on Abebooks, you might need a few more keywords though.

there's a thread in chat titled 'By the power of mumsnet!Mystery solving thread'. Try reposting on there-people are asking about loads of things and getting answers-someone on there found a book that I've been looking for for years! T
