Pierce Brown's 2014 debut novel, Red Rising, spawned a bestselling sci-fi universe, seized resounding critical acclaim, and generated an ardent fan base almost instantaneously. The operatic saga's dystopian setting, one defined by caste systems, mercurial intergalactic Houses, an uprising against a sadistic dictatorship, and young teenagers brutally fighting to the death, drew early comparisons to The Hunger Games by way of Star Wars. While formed around familiar concepts, Brown's premise — modeled after 19th-century Irish immigrants and "the disenfranchisement of working classes," as he told The New York Times — contains more distinctive substance than lackluster imitation.
