A Shadow Crown

A Shadow Crown is the second book in Melissa Blair's Halfling Saga, picking up where A Broken Blade left off. To the kingdom, Keera is the king's Blade, his most trusted spy and assassin. In secret, she works with Prince Killian and his Shadow, the Fae Riven, plotting to kill the tyrant king who holds her kingdom hostage.

Keera's past crimes against her own people have followed her to Myrelinth, a hidden tree city where Fae, Elves and Halflings live side by side. When a traitor is suspected among the conspirators, she becomes the prime suspect. She finds comfort in a chosen family, though she vowed never to open her heart again, and she has more to lose than she expected.

This is high fantasy with a slow-burn enemies-to-lovers romance between Keera and Riven, and it will suit readers of Sarah J. Maas's Throne of Glass series.
