I've not read White Boots before and the style is unmistakeably Streatfeild. She describes poor Harriet who has been very ill as feeling 'cotton-woolish and all-overish' and you know exactly what she means. Harriet's doctor advises skating lessons to build up the strength in her legs. Harriet's family cannot afford skates so her brother takes on a paper round to earn the two shillings necessary to hire them. Unfortunately these are hideous standard issue clumpy brown skates with a green circle of paint around the top to stop them from being stolen.
At the rink, Harriet meets Lalla, a girl of her own age who has an unlimited wardrobe, a Nanny, a Governess, a wealthy aunt fostering her skating career, private skating lessons and best of all, a pair of white boots! Lalla, although wealthy, is lonely and envies Harriet's large loving family. A close friendship develops between the two girls.
That's all I've read so far, I'll let you know how I get on. Reading Noel Streatfeild and L M Montgomery and Susan Coolidge lately has made me want to resurrect my shelved MA in Children's Literature and Culture but I'm not sure I can justify the expense.
