Humanx Commonwealth
Alan Dean Foster · 4 series · 29 novels · 1 novella · 4 novelettes · 5 short stories · 1972–2017
Two species that ought, by every buried instinct, to recoil from one another instead clasp hand to truhand and build a galaxy together. The Humanx Commonwealth is Alan Dean Foster's sun-warmed vision of a civilization founded jointly by humankind and the thranx — an insectoid people of poets and engineers whose partnership grows so intimate that the very word for it fuses the two. Across a scatter of settled worlds it is less an empire than a broad, well-meaning democracy, forever discovering that the universe is stranger, older, and far more crowded than its comfortable optimism assumed. The setting gathers decades of Foster's storytelling under one sky. Its longest thread follows Pip and Flinx — a red-haired orphan burdened with unnerving mental gifts, and Pip, the venomous flying minidrag coiled at his shoulder — from For Love of Mother-Not through more than a dozen restless adventures. The Icerigger trilogy strands shipwrecked traders on the frozen world of Tran-ky-ky; the Founding of the Commonwealth books (Phylogenesis, Dirge, Diuturnity's Dawn) reach back to how human and thranx first, warily, chose each other. Around these orbit standalone novels — Midworld, Cachalot, Nor Crystal Tears — each a self-contained plunge into one meticulously imagined ecology. What lingers is the biology. Foster builds living worlds first and plots through them second, so a jungle, an ocean planet, or an alien hive feels evolved rather than decorated, and the wonder is seldom at war with the peril. Newcomers may begin almost anywhere; the setting rewards wandering over sequence. There is no author-decreed order — publication order serves fine. For Flinx, open with For Love of Mother-Not; for a clean standalone taste, Icerigger; for the alliance told from the thranx side, Nor Crystal Tears.

✦ Curated by the Loreful team
10 works not in this orderNor Crystal Tears opens the sequence, showing first contact with the thranx from their own side before the Founding of the Commonwealth trilogy tells the same history from the human one. Pip & Flinx follows in the order Alan Dean Foster himself has recommended — starting with the prequel For Love of Mother-Not rather than the earlier-published The Tar-Aiym Krang. The remaining Commonwealth novels and the Icerigger trilogy are set in the same universe but follow neither cast; they close out the list as an optional tail, roughly in the order they were published.
