By Jean ThesmanApril 18, 1906. San Francisco is shaken by a nightmare earthquake. Its victims include two teenage girls-Kate Keely, an independent orphan, and fragile Jolie Logan, a scarlet fever survivor. Their lives collide when Kate is hired as Jolie's "personal companion"; before they have gotten used to each other, Jolie's father decides to send them to Ireland. Kate is ecstatic, until he entrusts her with the Logan family secret, one she must keep from Jolie. The girls make the exhausting journey by train and boat to Ireland, where they stay with Jolie's aunt, and thrive-in ways Dr. Logan would never have expected.
