|summary= World-building is the backbone by which fantasy novels live and die. And what a pleasure, then, to get a novel with world-building you actually want to delve into. Sarah Kozloff's debut novel presents a startlingly rich and layered world, with a complex history of connecting nations that seems certain to have more to tap, and the characters are interesting – if a little underdeveloped. But it's a world I could – and did – eagerly buy into, and the struggle of each Queen to discover and hone her magical talent felt very real and very apt.
