It only took 500-or-so episodes to revisit the world of Egan's Pulitzer Prize-winning novel A Visit from the Goon Squad. We did, of course, have to wait for Egan to write her sequel (sort of) novel. This follow-up to a post-postmodern classic is focused on memories (digital and otherwise) and relationships (virtual and otherwise). It's got "what if the Meta but for everyone's memories" okay??
