I thought to actually read the novel
Assassin's Creed was inspired by after having learned about it last year. The book,
Alamut by Slovenian
Vladimir Bartol (1903 – 1967), turned out to have a Finnish translation (by
Kari Klemelä). The covers had some background information like how the novel was mostly forgotten during Bartol's lifetime but was found again and became more widely known after the September 11 attacks.
