"The Priory of the Orange Tree" by Samantha Shannon (Preowned Paperback)

From the internationally bestselling author of The Bone Season, an enthralling epic fantasy about a world on the brink of war with dragons—and the women who must lead the fight to save it.

A world divided.

A queendom without an heir.

An ancient enemy awakens.

The House of Berethnet has ruled Inys for a thousand years. Still unwed, Queen Sabran the Ninth must conceive a daughter to protect her realm from destruction—but assassins are getting closer to her door. 

Ead Duryan is an outsider at court. Though she has risen to the position of lady-in-waiting, she is loyal to a hidden society of mages. Ead keeps a watchful eye on Sabran, secretly protecting her with forbidden magic.

Across the dark sea, Tané has trained all her life to be a dragonrider, but is forced to make a choice that could see her life unravel.

Meanwhile, the divided East and West refuse to parley, and forces of chaos are rising from their sleep.
