United by Blood. Divided by Duty. Bound by the Fate of a Kingdom.

When assassins strike down the King of Ostreich, the realm’s three princesses must face a truth they’ve long denied:

The greatest threat to the throne isn’t the enemy at the gates. It’s the rot within.

Commander Irmin rides the skies on wyvernback, ready to defend her people with steel and fire.

Scholar Adelinde searches for answers in the ravenglass network that binds rider to mount—answers that may cost her everything she loves.

Diplomat Elana fights to hold the court together as treachery spreads through the noble houses.

Separated by years of rivalry and mistrust, the sisters must learn to fight as one.

For only their united strength—mind to perceive, strength to act, will to bind—can stop a conspiracy that reaches from the palace halls to the wyvern roosts above.

From the winter solstice ritual deep beneath the capital to battles raging across sky and stone, the fight for Ostreich will test their courage, their loyalty, and their bond as sisters.

Because if they fail, the Kingdom will fall—and with it, every wyvern rider’s sacred bond.

The Ravenglass Throne: Parts 1–4 brings together the complete first arc of this epic nobledark fantasy serial—packed with political intrigue, wyvernbond magic, and a sisterhood forged in the crucible of war.

Perfect for fans of The Priory of the Orange Tree, The Goblin Emperor, and The Queen’s Thief, this is character driven epic fantasy where hope burns brightest against the dark.
