Playing Beatie Bow - Ruth Park I still love this book (it has been my fourth time now). Abigail is a kind of anti-heroine, but her personality is interestingly multi-faceted, Beatie and the rest of the Bow Family are so entertainingly vivid and Abigail's time-travel-experience is believably painted in loving detail (up to the accent of the Scottish immigrants and their Glasgow Marble patterned woolen stockings).
There is no denying that the ending is cotton candy pink; it successfully underlines the two - disputable - messages the author is trying to shout in our direction:
a) Real love on first sight exists
b) The ability to love deeply and truly is not connected to age or experience.
