Humanity X: Off the Ground — Book 1 of the Humanity X Trilogy by Donald Stelling & Landan Gibson. A grieving engineer joins the lunar build — and learns that crossing space is easy compared to building a future without repeating Earth's worst habits. Near-future hard-ish science fiction about building on the Moon, not space fantasy. Adam Voss, a young structural engineer, ships out on a multi-year contract to Artemis City after losing his family in an industrial disaster tied to the same corporate world that now employs him. Air, seals, and schedule pressure matter more than slogans about "the frontier." On Earth, rising Federal figure Marcus Hale sells the Moon as infrastructure and destiny. On the rock, Adam finds crew politics, failing seals, and a choice: keep quiet and survive, or build something honest in a place designed to hide the cost.
