Coming Apart — Ann M. Martin

When Nikki's father left her family, she thought all the trouble would be over. No more screaming. No more fighting. No more rages. But now he's coming back one last time, and Nikki isn't sure what's going to happen. Luckily, she has good friends like Flora, Ruby, and Olivia to stand behind her -- and a mom who cares about her kids enough to pull them through a hard time.
