Abigail

"You don't need any other friends. Friends back talk each other and fight and cause drama. They say they're there for you but they really aren't. They lie. They spread rumors. But I won't, Kendra. I'm not like them."
*****
Best friends Kendra and Millie have known each other forever, but their friendship is put to the ultimate test when Millie befriends the most popular girl in school and leaves Kendra behind. But Kendra meets a new friend too. Her name is Abigail, but she won't tell Kendra anything about her past or her life. Abigail is a very interesting person and helps Kendra break out of her shell and do things she never would have been brave enough to do before. At first, Abigail's adventures seem harmless, but after Kendra gets to know her new friend, she begins to question her definition of fun.
