Period Book

Or my favourite, "Lo, it rabbiteth again".

I was recommended the "The Night Templar" trilogy of books by a friend. It is about a Swedish guy (Arn) that could be a PC since it is optimized for his role (puissant single weapon et al) and goes from childhood in a monastery to crusades to blood feuds and to the creation of the realm of Sweden after going on crusade for a while.

The good thing is that the character is born 1150, so it is adequate for Ars period.

There is also a film about it:
