I don't remember them anymore, sadly. Summer Birds was the first, and so seminal for me as a kid reader. The others zoomed over my head, or seemed sad, or didn't quite work, though I did like Charlotte Sometimes. But not nearly as much as Summer Birds. (Which was one of the few books I wrote fic for as a child--the bird boy flew away to discover a gang of abused kids and rescued them. They never looked back.)
