Keira Sakurai is known throughout the kingdom of Matsu as the Ice Queen. A powerful warrior wielding devastating ice magic, she protects her people from the demons that threaten their world. She's fearless, determined, and always ready to put herself in harm's way.

Unfortunately, Keira has one troublesome weakness: she's far better at fighting demons than she is at understanding people.

When a mysterious attack damages one of the ancient crystal seals protecting the kingdom, Keira patches it with her magic, but can't fully restore it. With cracks appearing more often and demons beginning to slip through, she sets out to discover how the seals were created and how they can be repaired before it's too late.

Joined by four other mages, Keira travels across kingdoms in search of answers. Along the way, they'll face powerful demons, uncover secrets, and discover that the broken seals may be part of something far more dangerous than they imagined.
