I haven't got very far in this book, but wanted to write a review now. I like this series and would gladly give it another star, except for a glaring lack of understanding of the British education system.
State (public, if American) schools DO NOT charge tuition. Not any at all. They may charge for extracurricular activities, like day trips; but even then there's a hardship fund in most schools. It's not only poor children who go, either.
That, plus the fact that anyone with an American acquaintance, let alone friend, would know about Thanksgiving are irritants in what is usually a good series.
Or maybe this series is set in the 1930s? In which case, scrub the above and accept my apologies!
That apart, I do enjoy this series and am pleased that they're now all available for my Kindle (I've been told)
