Wake the Dream by Brea Viragh

Illaria’s only hope of escape is a man who may inadvertently lead her to death.
Illaria and her sister are Fae trapped in this world, hiding in plain sight. But when her sister goes missing, Illaria vows to do anything to bring her home. Even if that means teaming up with a human detective who would rather needle her than do his job.
Gifted with the Sight, Kieran Shanahan knows things others do not, which makes him the least popular man in the Marsh precinct. He’s given a case no one else wants, and in an attempt to prove his worth, he vows to solve it, even if it means dealing with a Fae who would rather decapitate him than sit on the sidelines.
Soon, the unlikely duo will have to work together to find Illaria’s sister. If they fail, someone…or something…will use them to destroy each other.
