Holly Black - A Novel of Elfhame Duology - The Stolen Heir and The Prisoner's Throne

The Stolen Heir - Eight years have passed since the Battle of the Serpent. But in the icy north, Lady Nore of the Court of Teeth has reclaimed the Ice Needle Citadel. There, she is using an ancient relic to create monsters of stick and snow who will do her bidding and exact her revenge.

Suren, child queen of the Court of Teeth and the one person with power over her mother, fled to the human world, where she lives feral in the woods.

Oak, now seventeen, is charming, beautiful and manipulative. He’s on a mission that will lead him into the citadel, and he wants Suren’s help. But if she agrees, it will mean guarding her heart against the boy she once knew and a prince she cannot trust, as well as confronting all the horrors she thought she’d left behind.

The Prisoner’s Throne - Prince Oak is paying for his betrayal. Imprisoned in the icy north and bound to the will of a monstrous new queen, he must rely on charm and calculation to survive. When High King Cardan and High Queen Jude go to extremes to retrieve their stolen heir, Oak must decide whether to attempt to regain the trust of the girl he’s always loved or remain loyal to Elfhame and end Wren’s reign - even if that means ending her too.

With a new war looming on the horizon and treachery lurking in every corner, neither Oak’s guile nor his wit will be enough to keep everyone he loves alive. It’s just a question of whom he will doom.
