From Madeleine L'Engle, Newbery medalist and author of the beloved classic, A Wrinkle in Time, comes this sensitive, well-written story of a young girl who unwittingly becomes involved in high-risk political and ecological intrigue, set against the starkly beautiful background of Antarctica. After a year spent in New York City with her family, Vicky Austin is bored with the quiet Connecticut village where she grew up. School has little savor, especially since her boyfriend, Adam has gone off, first to college and then to Antarctica on a research grant. Vicky whiles away the time writing in her journal and visiting Adam's great aunt Serena, a lively old woman who has taken a shine to her. Then Aunt Serena surprises Vicky by giving her a cruise through Antarctica as a birthday present. Vicky is thrilled. But abruptly Adam's letters — previously warm and affectionate — grow cryptic and cool. Then Vicky begins to receive warnings in the form of anonymous notes and postcards. She's not sure which of her fellow passengers on the Argosy to suspect, but soon her growing attraction to a handsome young prince leads her straight into the arms of danger, and she has cause to fear for her life. This is a story that is perfectly seasoned with just the right amount of everything: intrigue, romance, coming-of-age angst. Antarctica is vividly and compellingly rendered; the ecological concerns are timely; the characters fully realized and sensitively drawn. L'Engle is a master. (Fiction. 12+)
