Sky of Thorns by Fleur DeVillainy

The people of Kallistar believed the land was in peace… but darkness stirs in the North…

On the eve of the autumn equinox, unicorn shifter Sybil Vandeleur is kidnapped and stolen away to the Kingdom of Shadowvale, charged with treason against the crown. Only, she has never committed any crimes.

Aramis Adrastos, crown prince of Shadowvale, is told otherwise. Tasked by his father to capture the leader of a rebel group, he corners the woman planning to infiltrate the palace and take down the kingdom from the inside. But as soon as he lays eyes on her, destiny and duty become tangled with desire and need. She incites his anger, fills him with longing, and makes him question everything he believes in. Her very presence tempts him to betrayal. Chained in a dungeon, at the mercy of an evil queen, Sybil’s only hope for salvation lies with the prince who was raised to loathe her, just for being a shifter.

In a world strained from rebellion and rife with injustice, two adversaries fight to overcome their prejudices and face the true enemy before them.
