Fake Accounts by Lauren Oyler is a story about curating public personalities via social media, and how people do the same thing in face-to-face life. An unnamed female protagonist scrolls through her boyfriend’s phone and discovers he has a secret alternative identity on social media. Both she and the boyfriend are completely self-centered. The boyfriend stages his own fake death. Then the female protagonist, for no reason, invents fake identities for pointless Tinder dates. The boyfriend reappears from his fake death and they reunite, just as self-absorbed as they were in the beginning. The novel is non-stop snark, albeit skillfully written.
