Though most of Mrs. Whitney's best writing has been for the 12 to 16 group this younger story of 12 year old Cathy MacLeod, a Chicagoan with a strong Scotch heritage, combines mystery and personal growth to good advantage. Orphaned Cathy who lives with her Skyborn Grandmother has the opportunity of going on a trip with her relatives, the Corbins, who are going to Skye from Philadelphia. As a further surprise Cathy's Grandmother has made up a bundle of mysterious letters and packages for Cathy to open on the trip- each one of which will lead her closer to the heart of Skye. As it turns out, they lead her closer to friendship too. Cathy is able to soften the antagonism of her cousin Don Corbin, 13. Further credible adventures lead to Cathy's firm friendship with the Frasers, Morag and Raald, who are descendants in turn of a dear friend of her Grandmother's. Warm, polished storytelling.
