The Cycle of Oak Yew Ash and Rowan Books in Order

Queen Ysa uses dark magic and political schemes to secure her dynasty while the ancient houses of Ash and Rowan decline. A girl raised by a swamp healer may fulfill the prophecy that threatens the queen's grip on the throne.

After the king's death, Queen Ysa struggles to control her headstrong son and protect Rendel from an approaching northern evil. Ashen's royal blood, competing alliances, and unreliable magical help complicate the queen's increasingly precarious hold on power.

As Ice Dragon Riders threaten Rendel, earthquakes and volcanic activity unsettle the land. Rohan seeks allies among the Bog-folk, but Queen Ysa's rivalries obstruct the unity needed to confront the northern invasion and the evil behind it.

Ashen hopes her restored kingdom can finally enjoy peace, but the Mother Ice Dragon awakens to threaten it again. Finding the long-lost Dragon Blade becomes essential when legend offers no other weapon capable of defeating the ancient creature.

Ashen and Gaurin's peaceful kingdom faces new troubles as their children make dangerous choices. Elin pursues power through an evil alliance, while Mikkel's secret voyage aboard a Sea-Rover ship ends in captivity, threatening the family's hard-won stability.
