Penelope and Priscilla and the City of the Banished (Penelope and Priscilla)

The second book in the Penelope and Priscilla series of books. It's a steamy July, and while most kids are relaxing and enjoying their summer vacations, thirteen-year-old identical twins, Penelope and Priscilla Post, are spending much of their time learning about their heritage and strengthening their recently discovered powers. When the Post family celebrates their first year as residents in the eccentric town of Dunville with a family picnic, an ancient game leads the girls to discover that they have been drawn into a new mystery. A cryptic passage in the Enchanted Book and a visit to a very special bookstore reveal that something evil has come to Dunville. Now, as the girls prepare to start eighth grade, they are not only gearing up for a new school year and the inevitable ups and downs of friendships, new relationships and growing up, they are preparing for the battle of their lives.
