Vigil

A detective murder mystery featuring a flawed but likeable protagonist, with bonus fantasy worldbuilding

Half-human, half-weyrd Verity Fassbinder can walk the line between the denizens of those two worlds, and so she is entrusted by the supernatural creatures to keep the peace, shield the humans from becoming aware of them, and--when crimes involving the weyrd occur--investigating and ensuring that their fragile hidden existence is not threatened. When Sirens start being found dead and dying, horribly mutilated, it's up to Verity to find the culprit and stop them before an unthinkable confrontation between the two worlds occurs.

Even though I wouldn't call myself a fan of Urban Fantasy, I keep encountering books in that genre which I really enjoy. This is one of them. I tried it on the strength of really loving her 2015 novella Of Sorrow and Such, and I was glad that I did. It's a detective murder mystery featuring a flawed but likeable protagonist, with bonus fantasy worldbuilding--and if you think that might appeal, I strongly recommend this. The sequel, Corpselight, comes out in July 2017, and I will definitely be picking it up.
