From the back of Book 2 of the Secret Society Girl series, Under the Rose, by Diana Peterfreund:
Now a senior at Eli University, Amy is looking her future squarely in the eye—until someone starts selling society secrets. When a female member mysteriously disappears and a series of bizarre messages suggests conspiracy within the ranks, no member of Rose & Grave is safe . . . or above suspicion.
On Amy’s side, the other women in Rose & Grave remain loyal. Against her? A group of Rose & Grave’s überpowerful patriarchs who want their old boys’ club back. As new developments in her love life threaten to explode, and the search for the missing girl takes a disturbing turn, Amy will need to use every society maneuver she’s ever learned in order to stay one step ahead. Even if it means turning to old adversaries for help—or looking for her real enemies closer than she’d thought.
Under the Rose by Diana Peterfreund is available on iBooks or you can buy the Kindle edition from Amazon! (The paperback is also available from Amazon!)
