FROM UNSEEN FIRE by Cass Morris

A new review over at Tor.com:

These characters engage in political intrigue, magic, and war. In emotional terms, From Unseen Fire focuses on whether Latona will allow herself to claim ambition for herself—to move into spheres that custom and habit would deny her—and whether or not she’ll allow herself to act on her attraction to Sempronius Tarren. Meanwhile, Tarren is aiming at election to the praetorship, with an eye to having control of the legions in Iberia and advancing his ambitions for the future of Aven, but his enemies have no hesitation at stooping to dirty tricks to try to bar his way.
