A shadow crown
(Book)

"To the kingdom, Keera is the king's Blade, his most feared and trusted spy and assassin. But in the shadows, she works with Prince Killian and his Shadow--the dark, brooding Fae, Riven, who sets her blood on fire. Together, they plot to kill a tyrant king. In Myrelinth, the lush, secret city of trees, Fae, Elves, and Halflings like Keera live in harmony. But Keera cannot escape her past: her crimes against her own people have followed her all the way to the Faeland. There is a traitor in their midst, and Keera is the top suspect. Keera finds comfort in the allies that have become her family. She swore she would never open her heart again after a loss she barely survived. But she will soon find she has more to lose than she ever imagined..." -- Provided by publisher.
