The Upside of Falling plays on the fake-romance-turned-real, in which two parties decide–for one reason or another–that they should pretend to be a couple. Usually, chaos and hilarity ensue, along with some real-life unintended consequences. Ultimately, the two people end up developing real feelings for each other, and both have learned some lessons along the way. It’s a fun trope that leaves readers feeling optimistic and light-hearted.
