I'm trying to find a book I read years ago but can't remember the name of the author or book title
I can only remember bits out of the book:
The two main characters are traveling - they are guys and they end up together one has an unusual name, a herald in training I think. There was an ambush and people were killed with swords, bow and arrows and they have to taste the blood of the first person they killed or he will haunt them their entire life. Also, there are these cabin/houses that have different lights - the main guy asked what they meant and someone said if you dont know what they mean then you're too young to know.
