To Kill a Fae by C.S. Wilde

Fae enjoy playing dangerous games.

In detective Mera Maurea’s experience, three things motivated a murder: secrets, convenience, or passion. But none of the three can explain why the Summer King is dead.

With a tight deadline hanging over her head, Mera has to figure out who’s the culprit before the frail balance that holds the nation of Tagrad together crumbles into dust.
To aid her—or turn her life into a living hell, hard to tell which—is her fae partner Sebastian Dhay, a snarky detective with a penchant for the illegal. He’s a volatile wild card who will do anything to solve the murder, even if it means his doom.
The clock is ticking. And Mera is hiding a deadly secret of her own.
