On a planet stripped of wind, entire ecosystems lie in ashes, leaving humans to the mercy of a sole surviving bee species on a remote isle. Whoever wins the Praxis to rule them as Keeper, rules the world. When the next Keeper goes missing, her little sister must not only face her debilitating fear of bees, but compete in the Praxis to find her. As she braves the eerie fortress with sprawling wings of hives, murmuring murals, deceptive hedge mazes, and a host of leering gargoyles, she must also face the reigning Keeper, who’s guarding the darkest secret of all.
