I'm always game for a "found fiction" premise, and ASCENSION delivered an epistolary that kept me guessing til the end. Letters in a briefcase of questionable origin, chronology, and reliability tell the tale of a jack-of-all-trades scientist, running from his past and from epic loss, facing the insurmountable issues presented by a mountain that literally appears from nowhere. ASCENSION explores the issues of faith, humanity, and why we press on, despite all odds. Excellent narration, if you grab the audio version, like I did.
