Ritchie, Krista: - Krista & Becca Ritchie are New York Times and USA Today bestselling authors and identical twins--one a science nerd, the other a comic book geek--but with their shared passion for writing, they combined their mental powers as kids and have never stopped telling stories. Now in their twenties, they write about other twenty-somethings navigating through life, college, and romance. They love superheroes, flawed characters, and soul mate love.
