This character guide covers arcs across the whole book and may contain spoilers.

Thief of Hearts has a big, busy cast: warriors, royals, gods, thieves, dragons, and a few awful antagonists. Basileia anchors it as the battle-favored Thracian trying to lead her clan, with charming thief Zain and King Actos shaping much of the conflict around her.

On this page you'll find each character's role, a short description, and notes on their arcs and relationships, from Lia and Dione to the Thracian twins, the gods Invara and Eramis, and even Zain's dog Dagger. It's meant to help you keep the large cast straight without giving away the ending.
