The Priory of the Orange Tree (Roots of Chaos) by Samantha Shannon

From Bloomsbury Publishing

" The Priory of the Orange Tree isn't our grandfathers' epic fantasy novel. It is a clever combination of Elizabethan England, the legend of St. George and Eastern dragon lore, with a dash of Tolkien. Shannon's feminist saga has enough detailed world-building, breath-taking action and sweeping romance to remind epic fantasy readers of why they love the genre in the first place. Modern sensibilities integrate seamlessly with genre tropes . . . Readers will beg for a sequel." -- Shelf Awareness

"Shannon satisfyingly fills this massive standalone epic fantasy with court intrigue, travel through dangerous lands, fantastical religions, blood, love, and rhetoric." -- Publishers Weekly

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.
