Gorse is part fairy tale, part murder mystery. 
It's set in Cornwall in the 1780's. I initially thought this was a bit late for the old ways versus the church but I did research and discovered that Cornwall was full of heathens and loved an uprising. So well done Cornwall!
In Gorse someone, or something, is murdering people and the local religious types are blaming the Fae and saying they're demons. The local Keepers, Pel and Nancy, (who negotiate between the two worlds and keep both humans and Fae safe) think otherwise. Hijinks ensue (and by hijinks I mean violence)!
There's also a lot of beautiful descriptions of moorland; a very cute dog; and a boat load of toxic masculinity, although thankfully the female characters are having none of it!
The book deals a lot with grief, especially the loss of a child, and how it impacts the lives of everyone differently. Some coping in considerably less healthy ways than others!
I had a lot of fun reading it and now desperately need to read the second book in the series. Thanks very much to Solaris for an advanced copy. Please give me the next one now!
