As of my last update in early 2023, Alexis Smith is an American author best known for her debut novel "Glaciers," which was published in 2012. The book is a contemplative and elegantly structured narrative about a young woman's reflections on her life and unspooling desires set against the backdrop of a single day. Smith's writing is often characterized by its lyrical prose and intimate exploration of her characters' inner lives. Note that there may be more than one author by this name, and there may be updates or additional works by Alexis Smith beyond the scope of my current knowledge.
