Sister Fidelma's mysteries are always a travel in a remote and not well know age and in the Celtic Christianity.
I think I learn a lot and always had fun.
The well researched and vivid historical background, the fleshed out and interesting characters, the solid mystery that kept me guessing: I loved this things and I found this one of the best in this series.
Highly recommended.
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine
