Antonia Forest is very, very good - currently rereading Peter's Room.
But true, dyed-in-the-wool Chalet fans never really like them, as they are shocked that pious nice-girl Ann Marlow (who would be universally popular and beloved at the CS) is regarded as a do-gooder nuisance by her sisters and as tiresomely helpful by most of the Kingscote staff.
And that, when a disliked girl becomes ill and eventually dies, the former classmates who go around acting all shocked and as if they were her best friends, are regarded by the central characters as hypocrites, a judgement that the novelist doesn't entirely dislodge.
At the CS Marie Dobson would have been fervently prayed for by the entire school, then Joey would have come and broken it to her form in her golden voice that she had 'gone to sleep to wake with God', and everyone would have been sent to bed with hot milk and a dose, and been subdued for weeks. Then again, she would either have been reformed to make her likeable, or expelled as one of the tragic few the CS couldn't help, like Thekla von Stift.
But Antonia Forest fans like the grey areas of group and sibling psychology.
Though I do imagine it must have been a bit insufferable being a shy mediocrity who was in the same form as Nick, Tim and Miranda...
