Stump the Bookseller
New format, same book stumper solving.
Was she travelling alone? My first thought was Homecoming by Cynthia Voigt, but it’s a group of 2 brothers and 2 sisters. Their mentally ill mother abandons them, and they travel to their great-aunt’s.
This is a long shot, but this matches the beginning of The Silver Crown by Robert C. O’Brien. (Lots of other stuff happens, there are evil people tracking her, a big conspiracy is going on, etc. If your book is realism, this isn’t it.)
