A very solid and very accessible introduction to a bunch of different forms of theology that have developed in the 20th and 21st centuries. Johnson's explanations are pretty much always very, very clear for a lay audience, and she makes sure to include other accessible works in each further reading sections. If you want a starting place for modern Christian theologies, this really should be where you turn. Each section is both brief and manages to get a grasp on the debates at play, and I really can't emphasize those further reading sections enough. I will probably return to this book in the future because it's so useful and accessible.
