The Future of Us tells the story of best friends Emma and Josh. When Emma gets her first email account, a browser showing Facebook shows up on her screen. She looks into it and sees her future in fifteen years. Josh and Emma realize that changing little things in their present lives affects their futures in big ways. The two teenagers endure the normal challenges that face adolescents, but with the knowledge that they had gained about their futures. The book keeps you interested and makes you want the best for the characters. Though the ending is slightly predictable, I still felt myself smiling when I finished.
