In this sequel to What Katy Did, Katy Carr
has recovered from her long period of
paralysis, and is sent, along with her
sister Clover, to Hillsover boarding school.
The girls fall into friendship with the
mischievous Rose Red, and the three of
them start a secret club and get into
trouble with their teachers. During her
time at Hillsover, Katy has a positive
influence on the younger girls at the
school, while they help her to regain
some of her youthfulness, lost as a result
of her illness.
