Happily After All is one of the best Middle Grade books I've read, and I've read thousands.
I got it from the library because of the title, which is a clever referral to fairy tales. I loved it because of the characters, setting, and plot, all of which were excellent.
The book is about a girl who is sent to live with her birth mother after her father, who has had custody since she was a tiny tot, dies.
Becca doesn't want to go from sunny southern California to the woods of Vermont.
When she gets there she likes the horses, and does get to know some other kids, but is careful not to get close to anyone since she plans to return to CA.
Then she discovers some mysterious things about her own past and others about a boy in her class and is lead into danger.
I won't give away the plot but it's exciting, and I'm sure lots of kids would love this book.
Unfortunately, it was published in 1990, so it's probably be hard to find.
I googled the author's name, Laura C. Stevenson, and learned she's written a lot of other books since this one. She's a great writer, so I'll definitely try to read those.
