Quite a few Prometheus Award Best Novel winners, while not sequels themselves, have inspired subsequent novels that have received further Prometheus recognition.

Such winners by Sarah Hoyt (Darkship Thieves), Victor Milan (The Cybernetic Samurai) and Dani and Eytan Kollins (The Unincorporated Man) were examined in the previous post of this ongoing series about sequels.

Let’s turn our attention here to Prometheus-winning works by Ramez Naam and L. Neil Smith. Both authors were inspired to write more than one follow-up novel to their initial Prometheus-winning novels.
While Naam framed one complex story for his near-future Nexus trilogy, Smith conceived a variety of zestful and rambunctious stories all linked within his alternate-universe North American Confederacy series.
