In France, the brilliant young battle-mage Napoleon Bonaparte and has all but conquered Europe. Britain fights back, protected by the gulf of the channel and powerful fire-magic, but Wilberforce's own battle to bring about free magic and abolition has met a dead end. In Saint Domingue, Fina watches as Toussaint Louverture navigates these opposing forces to liberate the country. A sweeping tale of revolution and wonder in a world not quite like our own.
