Radicals, ion radicals, and triplets Book

It's interesting to read YA books written a long ago--you can see how styles have changed over time.

Nurse Matilda, is an old fashioned story about a family coping with naughty children. Brand never tells you how many children they are and she changes their names frequently. Not one child is developed as a character but neither is anyone else. The parents are colorless and unremarkable except for their utter cluelessness. The servants are many and equally undistinguished. Aunt Adeliade has some spark to her as the antagonist, but she barely has a cameo. There's no exploration of Nurse Matilda's back story or mythology.

I found this interesting for its place in history. I'd recommend it for that reason, but the story will bore modern readers.
