The Rook by Frost Kay

The Dark Court is no place for a lady.
After tricking the king, Tempest has finally won her long sought-after prize – a place on the king’s council – but it comes with a steep price. The king wishes for her to once again infiltrate the Jester’s Dark Court and crush the remaining rebellion. Stuck between her duty to her kingdom and her duty to what is right, she throws herself into the assignment, determined to discover her true enemies.

Slipping into her role as the Jester’s fiery plaything and personal warrior comes with an ease that terrifies her. The charming and dangerous shapeshifter makes it too easy to forget her purpose and tempts her to join his world of secrets and eternal night. But Tempest is no man’s pawn.

Her destiny was never to sit back passively. She makes her own path. Even if it’s painted with tears, strewn with regret, and scattered with the pieces of her broken heart.
