The Saddle Club is getting ready for the arrival of their friend Lady Theresa, otherwise known as Tessa, from England. She's going to be spending time in Willow Creek and they can't wait. To the Saddle Club it means fun, sleep-overs, and, of course, horses! To Veronica diAngelo, however, Tessa's arrival means a chance for revenge. She's never forgotten how this cousin to the Queen snubbed her when they were in England, but now it's her turn.
Will Veronica start a new revolutionary war? Or can the Saddle Club keep the peace?
