Some of the terminology [in When the Sirens Wailed] will be unfamiliar to readers (the wartime trains "is something chronic," a woman complains) but can usually be understood because of the context. Streatfeild's style is lively and her descriptions colorful; the characters are well-drawn and the dialogue is excellent. While the problems and fortunes of the children should engage readers, it is the atmosphere of wartime England—both in London and in the country—that gives the book its strength.
