A Canadian's third children's novel portrays an English girl who is unwillingly evacuated to Canada early in WW II. Stubborn and independent, Norah resents being put in charge of her sensitive five-year-old brother Gavin, whom she can barely tolerate. On arrival in Toronto after an arduous journey, she discovers that the two of them will be cared for by the Ogilvies--a formidable dowager and her grown, unmarried daughter. Both women clearly favor Gavin. On top of that, Norah's nature soon puts her at odds with Mrs. Ogilvie's overweening personality and brings her difficulties at school as well. When a near disastrous prank threatens to deny her the company of the few friends she has managed to make, she determines to run away--only to be confronted by the reality that she herself bears at least half the responsibility for her problems. Although Norah is not a likable character, her growth--as well as Mrs. Ogilvie's--is the chief strength here. Pearson's prose is serviceable at best, but it does delineate the setting effectively, and Norah's story is involving enough to hold attention.
