I'm a huge Tana French fan, myself. Highly recommend her Dublin Murder Squad series.
I think I will check Tana French out: Any reason not to start with In The Woods?
I think you mean In The Forest. I especially enjoyed her last novel,The Little Red Chairs. Her writing is special. That's funny. Tara French wrote In The Woods and Edna O'Brien wrote In The Forest. A little confusing.
In the Woods is Tana French's first book. Yes, start with that. And enjoy!!
If anyone is in the mood for dark but fun Irish novels, you can't go wrong with Adrian McKinty or Ken Bruen, in my humble opinion
