I enjoyed The Overstory, but thought it was a bit overstuffed with characters and could have used a better editor. The author must have gotten that feedback from others, because Playground gets it just right. It's a little too on-the-nose with setting up characters who represent opposing views of "technology will save us" versus "technology will ruin us," but I loved the way the story unfolded and the lyrical descriptions of the underwater world.
