The Vassal of the Endless (#3)

Finn and his friends and fellow members of the Valdar—Tristan, Emma, and Gwen—have finally tracked down Grid, a Vanaheim who pretended to be their friend and is trying to steal the sacred Grimoire spellbook for her own purposes.

But Grid is the powerful ruler of the realm they have found her in and she won’t be easily captured. Instead, Grid kidnaps Gwen and plans to marry her off to expand her power in the realm. With Gwen in the enemy’s clutches, it’s up to Finn and the Valdar to spark a revolution to stop the wedding and end Grid’s reign.
