Katy Carr can hardly believe it when she is invited to spend a whole year in Europe with Mrs Ashe and Amy. Although a year seems like a long time away from her beloved family, living in the small American town of Burnet, Katy embarks enthusiastically on her greatest adventure. This charming story, first published in 1886, is the third of Susan Coolidge's three hugely popular Katy books.

Susan Coolidge (Sarah Chauncey Woolsey) is best known for her classic children's novel What Katy Did (1872). The fictional Carr family was modelled after the author's own, with Katy Carr inspired by Susan (Sarah) herself, and the brothers and sisters modelled on Coolidge's Woolsey siblings. Two sequels follow Katy as she grows up: What Katy Did at School (1873) and What Katy Did Next (1886). Two further sequels were also published: Clover (1888) and In the High Valley (1890).
