Her book "Croatian Tales of Long Ago" ("Priče iz davnine"), published in 1916, is among the most popular today in large part because of its adaptation into a computerized interactive fiction product by Helena Bulaja in 2003/2006. In the book Mažuranić created a series of new fairy-tales, but using names and motifs from the Slavic mythology of Croats. It was this that earned her comparisons to Hans Christian Andersen and Tolkien who also wrote completely new stories but based in some elements of real mythology.
