A Message in Blood

the author does give a trigger warning at the beginning of this book it is a rough book to get into the topic is something that we all displease of but it's still a good mystery and I highly recommend this in a series as well but if you are sensitive triggers definitely pay attention to the author's warning at the beginning and if you want to know exactly what the warning is about before reading it or buying it I believe it's in the first sample as a eBook so you can get the sample from Amazon or whatever and see if a warning is in there before reading it but it is in the author's notes right before the first chapter other than that this is a really good book despite the tough topic and it goes really well with the series.
