Synopsis: "Such things are only in Krakow! The young CBŚ agent, Katarzyna, her immortal cousin Stanisława and the Serbian princess, saved by Polish soldiers, the undead Monika Stiepankovic - on the trail of the alchemist Sędziwoj and the legend of the powerful power of the philosopher's stone. Here is a story in which computer science and alchemy meet, a scimitar steel dagger rests beside a loaded pistol, and a saber is used as often and easily as a laptop. Here is a story of friendship, sacrifice, magic and a wonderful royal city." Goodreads July 3, 2021
