Eighteen-year-old Robert Weekes is one of the few men who practice empirical philosophy--an arcane, female-dominated branch of science used to summon the wind, heal the injured, and even fly. He's always dreamed of being the first man to join the US Sigilry Corps' Rescue and Evacuation Department, an elite team of flying medics, but everyone knows that's impossible: men can barely get off the ground. When a shocking tragedy puts Robert's philosophical abilities to the test, he rises to the occasion and wins a scholarship to study philosophy at Radcliffe College--an all-women's school. At Radcliffe, Robert hones his flying skills and strives to win the respect of his classmates, a host of formidable and unruly women. Robert falls hard for Danielle Hardin, a disillusioned young hero of the Great War turned political radical. But Danielle's activism and Robert's recklessness attract the attention of the same fanatical anti-philosophical group that Robert's mother fought against decades before. With their lives in mounting danger, Robert and Danielle band together with a team of unlikely heroes to fight for Robert's place among the next generation of empirical philosophers--and for philosophy's very survival against the men who would destroy it.
