THE ICE CHILD

English author McGregor makes her US debut with three books in one: the story of a wandering polar bear; a fictionalized account of Sir John Franklin’s doomed 1845 expedition in search of the Northwest Passage; and, last but not least, a modern-day tearjerker.

Sam Marshall, a two-year-old stricken with aplastic anemia, will die unless a bone-marrow donor can be found. The nearest match may well be his much older half-brother John, a marine archaeologist who’s now lost somewhere in the Arctic while he looks for traces of the Franklin Expedition. Sam's mother, Jo Harper, the young and lovely widow of BBC-TV commentator and marine archaeologist Douglas Marshall, angered John's mother, Alicia, several years ago when Jo came to interview her about her famous ex-husband. And that was before Jo fell in love with Doug, who then died in a car crash that spared his grown son. The first Mrs. Marshall still hasn't gotten over her pique at her ex's lifelong obsession with the Franklin Expedition, and she's not about to help Jo find John. But there are others who will, among them Catherine Takkiruq, the half-Inuit beauty who loves John and is conveniently nearby in London. The race to find the young man begins, although no one knows for certain whether he's a match for Sam. Or whether Sam will even survive. See Sam waste away pathetically (and much more quickly than most victims of aplastic anemia would, the author notes coyly in an afterword). See the majestic polar bear stride across the frozen waste. See the stalwart 19th-century explorers perish one by one from cold and disease and starvation. See the author do her hardest to tie this triple-threat plot together in every possible way: the polar bear is a mother too, with a sick cub.

Hopelessly contrived.
