On April 18, 1906, San Francisco was thrown into crisis by a powerful earthquake. Buildings fell, fires burned, riots broke out, and at least 3000 people died. Kate, a poor, strong-willed orphan, and Jolie, a spoiled semi-invalid, are both left temporarily homeless amid this chaos. Kate longs to escape San Francisco to her mother’s homeland of Ireland, while Jolie becomes determined to return to her life as it was before the quake. When the two girls meet, they do not like each other. But as their friendship builds, both learn that returning to the past is not as easy as they would hope.
