The science fiction book series 'Dungeon Crawler Carl,' by Matt Dinniman, confronts readers with existential questions within the LitRPG genre. LitRPG, a fusion of literary role-playing games, science fiction, and fantasy, is explored through the lens of Earth's near-destruction by aliens. The series follows the protagonist, Carl, and Princess Donut, his ex-girlfriend’s cat, as they are forced to participate in a survival game reminiscent of reality TV and video game dungeon crawls. The audiobook version, voiced by Jeff Hays, is particularly recommended for its distinct character portrayals. In addition to book recommendations, the author also highlighted the notetaking app Obsidian, praising its customizability and convenience for tracking notes, reading habits, fitness goals, and work tasks. Its open-source nature and local file storage ensure data privacy. Lastly, the author recommends the birding app Merlin, from the Cornell Lab of Ornithology, for identifying bird species through photos, step-by-step questions, or audio recordings. The audio analysis feature allows real-time identification of birds singing nearby.
