Rein it in

The A circuit's notorious new gossip blog is all anyone can talk about.

Rumors about Kate are threatening her horse show career and her relationship with Fitz.

Zara is mad when her riding ability is questioned. Tommi is riding the high of selling the horse she trained all summer.

But the blog is speculating about her next training prospect . . . and a new guy she meets at the first show of the fall season.

He's a star athlete, but is he boyfriend material? As the exclusive series of fall horse shows known as Indoors kicks into high gear, so does the gossip. And when the blogger posts a fake scandal about Zara's rock star father, she knows things have gone too far. And she has a plan to out the snarky blogger once and for all. . . .
