It's a little after the middle of the 21st century. Loving couple Elspeth and Marybeth are both shocked and excited when a stroller with identical twins is left on their back deck with a recorded message that warns them not to try to return the babies or they could face arrest for kidnapping. Using false starts, footnotes, direct approaches to the reader, lists, questions about who the author(s) might be, and even a dose of self-criticism, the story unwinds from that point as El and Mar work hard to create a family under the circumstances. This becomes even more difficult when they discover the babies come with unusual features that perhaps might explain why they were left in the first place. And it all takes place in a disintegrating world that may leave humans incapable of telling their own stories.
