Twelve-year-old Katherine Ann Stephenson has just discovered that she's inherited her late mother's magical talents, and despite Stepmama's stern objections, she's determined to learn how to use them. But with her eldest sister Elissa's intended fiancé, the sinister Sir Neville, showing a dangerous interest in Kat's magical potential; her other sister, Angeline, wreaking romantic havoc with her own witchcraft; and a highwayman lurking in the forest, Kat's reckless heroism will be tested to the utmost. If she can learn to control her new powers, will Kat be able to rescue her family and win her sisters their true loves?

In this charming blend of Jane Austen-era culture, magical whimsy, and rollicking adventure, readers will find a true friend in the refreshingly unladylike Kat Stephenson.
