The Shards of Magic follows Kenna Heron from servant to princess to warrior in Mistei, the Fae kingdom under the earth. Servant of Earth (2024) traps her in a set of six trials, one per Fae house, with a rebellion growing around her. Princess of Blood (2025) turns the story into a three-way fight for the throne with Kenna holding the deciding vote. Warrior of the Shards closes the trilogy on December 8, 2026, with Mistei at civil war.
Read them in order. It is darker than Hawley's Glimmer Falls romcoms, with on-page violence and a slow burn that pays off across all three books. If you like the trials in The Serpent and the Wings of Night, this is a strong next pick.
