a school for juvenile delinquents. Macey, Bex, and Liz go shut down the defenses and keep an eye on security, leaving Zach and Cammie alone to complete the mission. Zach asks Cammie to stay, wanting her to be safe, but she responds by kissing him and asks where they are going. "The Tombs," is his reply. Zach and Cammie go out to the woods and find the entrance to "The Tombs". The make their way through a complicated maze and Zach reveals that Blackthorne is a school for assassins. They finally find the place where Joe Solomon's journal is hidden and retrieve it. As they are about to leave, they hear people coming and hide. They see several members of the Circle of Cavan, including the woman who tried to abduct Cammie from the roof in Boston last summer, and Joe Solomon. The explosives on the walls show that Mr. Solomon brought the members here to kill them and himself in the process. A man finds Cammie and Zach and brings them to the woman. We learn that she is Zach's mom, and Cammie is horrified. After a quick fight Zach manages to get a gun and take aim at the explosives. Cammie says "NO!" but cannot stop Zach, so she begins to run. She thought she had made it out but ran into Zach's mother, and we learn that she was a Gallagher Girl. She tries to convince Cammie to come to her by telling her that her father is still alive.

Cammie gives Zach the journal before being ambushed by her distressed roommates. Cammie decides she will not be able to go to her grandparents' ranch this summer because it is too dangerous. One day Cammie and Zach talk, and Zach
